<span style="font-family: "Georgia",serif; font-size: 12.0pt; mso-bidi-font-size: 11.0pt;">Like garden hoses, electrical
wires are only designed to carry a limited amount of current to prevent short
circuits. Unlike water and garden hoses, however, the current capacity of a
wire is not directly proportional to the gauge.<o:p></o:p></span></div>
<div class="MsoNormal" style="text-align: justify;">
<br /></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "Georgia",serif; font-size: 12.0pt; mso-bidi-font-size: 11.0pt;">A six-gauge wire
(American Wire Gauge standards), for instance, has a 4.11mm diameter and a
current capacity of 37 amps for power transmission, while a twelve-gauge wire
only has a 2.05mm diameter and 9.3 amps—more than half the capacity. This isn't
just because the wire is smaller; the electrical resistance grows as it
shrinks.</span></div>
<a name='more'></a><br /><o:p></o:p>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "Georgia",serif; font-size: 12.0pt; mso-bidi-font-size: 11.0pt;">At 1.588 ohms per 1,000
ft., the twelve-gauge wire has more resistance than the six-gauge at 1.296 ohms
per 1,000 ft. The resistivity of the wire becomes more concentrated in a
smaller cross-section, and will increase with the length of the wire. By
widening the wire's cross-section and shortening the wire, resistivity can be
dispersed and weakened.<o:p></o:p></span></div>
<div class="MsoNormal" style="text-align: justify;">
<br /></div>
<div class="MsoNormal" style="text-align: justify;">
<span style="font-family: "Georgia",serif; font-size: 12.0pt; mso-bidi-font-size: 11.0pt;">Current sensors from
power monitoring device suppliers keep track of the current flowing through an
electrical load to protect it from short circuits. An overcurrent or
overvoltage can cause serious damage to the local grid, resulting in costly
repairs, if not fires. The data can be used to improve electrical systems, like
installing the correct resistors to control electrical energy. <o:p></o:p></span></div>

<span style="font-family: "Georgia",serif; font-size: 12.0pt; mso-bidi-font-family: Arial; mso-bidi-font-size: 11.0pt;">It’s not difficult to distinguish alternating current from direct
current. By observing how some electricity-powered appliances in your home function,
you can tell which ones use AC or DC by their distance from the power source.
Those plugged farther away from the power source use AC, while those connected
directly to the source use DC.</span></div>
<a name='more'></a><br /><o:p></o:p>
<div class="MsoNoSpacing" style="text-align: justify;">
<span style="font-family: "Georgia",serif; font-size: 12.0pt; mso-bidi-font-family: Arial; mso-bidi-font-size: 11.0pt;">You television, for instance, uses AC because it’s powered through a
plug that goes into the wall. The best example of a device in your home that
uses DC is your flashlight. It’s not plugged anywhere and gets its power from
the batteries inside it, which produces DC. You can simply assume that any
appliance or device that gets its power from batteries uses DC.<o:p></o:p></span></div>
<div class="MsoNoSpacing" style="text-align: justify;">
<br /></div>
<div class="MsoNoSpacing" style="text-align: justify;">
<span style="font-family: "Georgia",serif; font-size: 12.0pt; mso-bidi-font-family: Arial; mso-bidi-font-size: 11.0pt;">Meanwhile, certain devices in your home use both DC and AC. Your laptop
and cellphone, for instance, use DC but have to be plugged into an AC source to
recharge. If you’ve read about the basics of electricity, you know that only DC
can be stored, so why charge a battery from an AC source?</span></div>
<br />
<div class="MsoNoSpacing" style="text-align: justify;">
<span style="font-family: "Georgia",serif; font-size: 12.0pt; mso-bidi-font-family: Arial; mso-bidi-font-size: 11.0pt;">Well, this is because the charger you plug into the wall consists of
rectifiers, whose main function is to transform AC into DC as they enter the
batteries of your devices. These rectifiers, however, cannot transform the
dangerous currents coming from the electrical source and flowing directly into
the charger, which is why the charger also has a current transformer in it.<o:p></o:p></span></div>

<span style="font-family: "Georgia",serif; font-size: 12.0pt; mso-bidi-font-size: 11.0pt; mso-font-kerning: 11.0pt;">As
the name implies, protection current transformers are used to protect
electrical systems from damage. They reduce the high current flowing in a power
system element to lower, manageable values ideal for relay operation.
Protective CTs from power monitoring equipment providers can also isolate the
relay circuit from the primary, while allowing for the use of standardized
current rating for relays, which can either be 5 or 1 ampere.</span></div>

designed for high-current relaying and metering applications. They come in two
types: the wound and the bar-primary type with secondary cores. Wound current
transformers have a primary winding that’s physically connected in series to the
conductor carrying the measured current flowing in a given circuit. Bar-types,
on the other hand, use the main circuit’s actual cable as primary winding. Both
employ the single-phase method. <o:p></o:p></span></div>

<span style="font-family: "Georgia",serif; font-size: 12.0pt; mso-bidi-font-size: 11.0pt; mso-font-kerning: 11.0pt;">Outdoor
CTs are generally used for metering and relaying circuits. They employ three-phase
and single-phase method up to 33 kilovolts (kV), and are magnetic in nature.
They usually come in three types: capacitor, oil-filled, and combined current
and voltage transformer. <o:p></o:p></span></div>

are also outdoor CTs that exceed the 33 kV limit. All employ the single-phase
method and come in two general types: magnetic and capacitor voltage
transformer (CVT).<o:p></o:p></span></div>

<span style="font-family: "Georgia",serif; font-size: 12.0pt; mso-bidi-font-size: 11.0pt; mso-font-kerning: 11.0pt;">Ensuring
the safety of measuring large currents in industrial settings presents many
challenges. For one, measuring a large voltage via small burden resistors in a
circuit is not only ineffective, but also potentially hazardous. Common current
measuring instruments can typically measure a few amperes, but you can’t use
them for long. Prolonged use may lead to damaged equipment, or worse, physical
injury.</span></div>
<a name='more'></a><br /><o:p></o:p>
<div class="MsoBodyText" style="text-align: justify;">
<span style="font-family: "Georgia",serif; font-size: 12.0pt; mso-bidi-font-size: 11.0pt; mso-font-kerning: 11.0pt;">Fortunately,
high currents can be measured through more practical means, one of which is the
use of current transformers. CTs are sensing devices that can reduce the level
of current to more manageable levels. They come in different types, but the two
most often used are the split core and the solid core CTs.<o:p></o:p></span></div>
<div class="MsoBodyText" style="text-align: justify;">

<span style="font-family: "Georgia",serif; font-size: 12.0pt; mso-bidi-font-size: 11.0pt; mso-font-kerning: 11.0pt;">Split
core transformers are considered more practical when installing CTs in existing
circuitry, as they can be installed without the need to disrupt the circuit.
Solid core CTs, on the other hand, require some rewiring. In terms of cost,
split core CTs are pricier, but the fact that they can be easily attached to a
circuit means you get to save time, effort, and money in their installation. <o:p></o:p></span></div>

core transformers from power monitoring system suppliers, meanwhile, are
capable of more precise current measurements, making them the preferred choice
in situations where extreme accuracy is necessary.<o:p></o:p></span></div>

Global energy demand will continue to increase due to population growth. In a recent Hydrocarbon Engineering report, Emma McAleavey writes that even with energy efficiency measures in place, residential, commercial, and industrial demand for energy will grow between 2010 and 2040. Fortunately, North America and Europe will see the lowest increase in demand. Building code updates, energy efficiency mandates, and investment in alternative sources of energy are able to keep the rate of increase down to 20 percent. McAleavey reports, though, that it could’ve been 50 percent—at par with Asia, a budding mega-economy.<br />

The first step in mitigating power surges is to recognize that they are sometimes inevitable and thereby spell the need to install a flexible current transformer. Such a device is commonly used to measure surge currents. Aside from utility works, power surges can also be caused by lightning or internal circuitry (e.g. activating high-powered systems). The next step is to identify the cause. If the facility is experiencing power surges on a clear day, lightning is unlikely to be the culprit. Experts believe most power surges stem from within a facility, such as a faulty wire or tripped circuit breaker somewhere. You can use the readings on the current transformer to determine fluctuations in a conductor’s current.<br />

<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">Position
can be determined via one of two ways—either by determining
‘distance’ (the length of separation between two points) or by
‘rotation’ (angular movement). Sensors that are positional in
nature can detect the movement of an object using linear sensors that
employ the distance method or through rotational sensors that compute
for rotation.</span></span></div>
<div align="justify" class="western" style="line-height: 150%;">
<br />
</div>
<div align="justify" class="western" style="line-height: 150%;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">One
type of positional sensor is the “Linear Variable Differential
Transformer (LDVT), an inductive-type sensor that functions similar
to the AC transformer when it comes to measuring movement. A common
type of inductive positional sensor is the Eddy current sensor, which
is mainly used to detect objects in close proximity. Due to this
characteristic, Eddy sensors earned the more popular moniker
‘proximity sensors’.</span></span></div>
<a name='more'></a><br />
<div align="justify" class="western" style="line-height: 150%;">
<span style="font-family: Georgia, serif; font-size: 12pt; line-height: 150%;">Eddy
current sensors are non-contact inductive positional sensors that
detect current via a magnetic field with the reed switch acting as
the simplest magnetic sensor. This type of sensor employs a coil
that’s wound around an iron core within an electromagnetic field to
create an inductive loop.</span></div>
<div align="justify" class="western" style="line-height: 150%;">
<br />
</div>
<div align="justify" class="western" style="line-height: 150%;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">Inductive
proximity sensors operate under the principle of Faraday’s Law of
Inductance. When a ferromagnetic material such as a plate or screw is
placed within the Eddy current field generated around the sensor, the
coil’s inductance varies significantly. The sensor’s circuit
detects this variation and thus produces an output voltage. </span></span>

(CT) are generally used to measure and control current in an
electrical system. High current levels cannot be fed to a system’s
relays and meters, and it’s a CT’s job to quantify our manipulate
current to a level that these devices can handle. Based on function,
CTs can be classified as follows:</span></span></div>
<div align="justify" class="western" style="line-height: 150%;">
<br />
</div>
<div align="justify" class="western" style="line-height: 150%;">

<div align="justify" class="western" style="line-height: 150%;">
<br />
</div>
<div align="justify" class="western" style="line-height: 150%;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">This
type of CT is typically used in combination with measuring devices
for the accurate measurement of energy, current, and power.</span></span></div>
<a name='more'></a><br />
<div align="justify" class="western" style="line-height: 150%;">
<b style="font-family: Georgia, serif; font-size: 12pt; line-height: 150%;">Protective
CTs</b></div>
<div align="justify" class="western" style="line-height: 150%;">
<br />
</div>
<div align="justify" class="western" style="line-height: 150%;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">Protective
CT types are used in combination with protective devices such as trip
coils and relays. Protective CTs can be further classified into three
distinct categories, namely: Bar Type, Wound Type, and Window Type. </span></span>
</div>
<div align="justify" class="western" style="line-height: 150%;">
<br />
</div>
<div align="justify" class="western" style="line-height: 150%;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">To
differentiate between the three: Bar Type is a CT that consists of a
bar and a material that comprises the integral part of the
transformer. Wound Type contains a primary winding of ore instead of
a full turn wound over the core. Window Type on the other hand, has
no primary winding, with the secondary winding placed around the
current.</span></span></div>
<div align="justify" class="western" style="line-height: 150%;">
<br />
</div>
<br />
<div align="justify" class="western" style="line-height: 150%;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">The
basic principle behind CTs follows that of the power transformer.
Like the latter, all CTs also have primary and secondary winding,
with the exception of the Window Type Protective CT.</span></span></div>

<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">At
the heart of a current transformer is a slab of magnetic material
known as a magnetic core. to put it simply, the measurement mechanism
wouldn't work without a magnetic core.</span></span></div>
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<br />
</div>
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">Enveloped
by two upper layers of insulation and secondary windings, the
magnetic core emits the magnetic field necessary to generate
electromagnetic energy. Through the Hall Effect, the current
transformer enables a hooked measuring device like an ammeter or
voltmeter to get accurate readings. Solid and split-core transformers
are known to employ magnetic cores.</span></span></div>
<a name='more'></a><br />
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<span style="font-family: Georgia, serif; font-size: 12pt; line-height: 150%;">Although
not the most magnetic metal on Earth, iron is commonly used as a
magnetic core material. Aside from its well-known magnetic
properties, iron can handle high power outputs rather well, making it
ideal for non-measurement functions as well. An iron core may also be
any one of these kinds of alloys designed for optimum performance.</span></div>
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<br />
</div>
<br />
<ul>
<li>
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">FeSi
core – The most affordable of its kind but rather unwieldy, apart
from its poor performance at low currents. Commonly used for
protecting power grids with high currents.</span></span></div>
</li>
<li>
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">FeNi
core – The best there is, although the most expensive. Prevalent
in current transformer systems, especially for laboratory
applications where high accuracy is a must.</span></span></div>
</li>
<li>
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">Ferrite
core – Once considered low quality for their poor magnetic
permeability, this core has been considerably improved by
technology. Their high performance for low cost also has utility
services thinking about bigger ferrite core transformers. </span></span>

<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">Accuracy
is, and probably will always be, a contested subject. Even the
readings on the most sensitive gauges ever made will be subject to
factors beyond anyone's control. This is why it's reasonable to
consider a margin of error every time you take a measurement,
especially when it comes to currents.</span></span></div>
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<br />
</div>
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">Given
that current transformers are always on the lookout for unusual
energy spikes, accuracy must be their most defining feature. They
don't have to be perfectly accurate, just accurate enough to confirm
the readings and help managers make sound decisions. However, no
one-size-fits-all transformer exists at present.</span></span></div>
<a name='more'></a><br />
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<span style="font-family: Georgia, serif; font-size: 12pt; line-height: 150%;">There
are several accuracy classes, depending on who you ask. IEC 60044-1,
the more widely used standard, enumerates 11 accuracy classes. IEEE
C57.13 enumerates 10 classes. For the purposes of clarity, take IEC
60044-1 as an example. By order of highest accuracy, current
transformers are usually concerned with only the four topmost
classes.</span></div>
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<br />
</div>
<ul>
<li>
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">0.1
– 0.1 to 0.4 ratio error, 5 to 15 minutes phase displacement</span></span></div>
</li>
<li>
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">0.2
– 0.2 to 0.75 ratio error, 10 to 30 minutes phase displacement</span></span></div>
</li>
<li>
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">0.5
– 0.5 to 1.5 ratio error, 30 to 90 minutes phase displacement</span></span></div>
</li>
<li>
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">1.0
– 1.0 to 3.0 ratio error, 60 to 180 minutes phase displacement</span></span></div>
</li>
</ul>
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<br />
</div>
<br />
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">Some
might think that it's simple to get a 0.1-class transformer, but this
choice depends on the nature of the application. The less accurate
classes, for instance, are primarily used for surge protection. The
0.1-class transformer, on the other hand, is necessary for laboratory
use due to its low ratio error.</span></span></div>

Any type of current flow creates a proportional magnetic field, and DC
current transducer products measure this generated field using Hall
Effect technology. Hall Effect is defined as the generation of a
magnetic field perpendicular to the current and a voltage difference
across an electrical conductor transverse to an electrical current in
the conductor.<br />
<br />
This article discusses how Hall Effect devices
work, their limitations, and how they can be improved.Understanding Hall
Effect devicesA Hall Effect-based transducer, such as the one contained
in a RōCoil TCA-5-HV-KIT, is generally composed of a signal
conditioning circuitry, a core, and a Hall Effect device.<br />

<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">There
are many different </span></span><span style="color: navy;"><span lang="zxx"><u><a class="western" href="http://www.aimdynamics.com/"><span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">types
of sensors</span></span></a></u></span></span><span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">
and transducers, but in general, all of them can be classified into
two basic types: analog and digital. So which one is more useful to
your needs? Find out below.</span></span></div>
<div align="justify" class="western" style="line-height: 150%;">

<div align="justify" class="western" style="line-height: 150%;">
<br />
</div>
<div align="justify" class="western" style="line-height: 150%;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">Analog
sensors create continuous and generally proportional output signal to
that of the quantity being measured. Physical quantities such as
Strain, Temperature, Pressure, Displacement and Strain, among others,
are all analog because of their continuous characteristic. Analog
sensors share this continuous nature, producing signals that change
smoothly over time.</span></span></div>
<a name='more'></a><br />
<div align="justify" class="western" style="line-height: 150%;">
<b style="font-family: Georgia, serif; font-size: 12pt; line-height: 150%;">Digital
sensors</b></div>
<div align="justify" class="western" style="line-height: 150%;">
<br />
</div>
<div align="justify" class="western" style="line-height: 150%;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">Digital
sensors produce distinct digital output signals that represent the
digital form of the quantity being measured. This type of sensor
generates a binary output signal in the form of 1s and 0s. This means
that the digital sensor only produces, distinct, non-continuous
values which may be outputted as a single serial transmission (bit)
or parallel transmission (byte).</span></span></div>
<div align="justify" class="western" style="line-height: 150%;">
<br />
</div>
<br />
<div align="justify" class="western" style="line-height: 150%;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">Compared
to analog, sensors of the digital variety score high in accuracy and
can measure and sample signals at a much faster rate—usually
millions of times faster than analog signals. To be able to produce
electrical signals that can be used and measured, analog sensors
require additional amplification or filtering of the signal and an
external power supply.</span></span></div>

<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">Current
transformers can be hooked up to an ammeter, although the resulting
amperage reading only paints a partial picture of an office or
factory's energy consumption. A gauge system brings out the
transformer’s full potential by providing real-time data that
includes amperage, voltage, frequency, power factor, and more. Access
the data on the computer, and you'll get a bird's-eye-view of your
power consumption patterns.</span></span></div>
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<br />
</div>
<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<span style="font-family: Georgia, serif;"><span style="font-size: 12pt;">A
gauge system is a mother unit that can support a number of
conductors. It gathers data from all connected units and, depending
on the model, may upload the data on the Internet through an Ethernet
connection. This enables the user to access the information, whether
onsite or offsite, and make quick decisions.</span></span></div>

<div align="justify" class="western" style="line-height: 150%; margin-bottom: 0in;">
<span style="font-family: Georgia, serif; font-size: 12pt; line-height: 150%;">Such
a system records more than just power consumption. Advanced
algorithms allow the unit to compute for energy efficiency from the
time the unit came online. The Web interface automatically calculates
how much energy was used or saved over a given period and how much
these figures translate to dollars (based on current rates).</span></div>

Thanks to digital metering made possible by modern AC and DC current sensor technology, charges have become smaller and less expensive. Split-core sensors operate around the milliamp range, as opposed to solid-core ones. Split-core sensors are ideal for measuring ACs, given their nature of changing currents often. Despite operating at a measly 333 mV, they’re rated to measure inputs of up to 1,500 amps depending on the diameter of the measuring field. The good thing about this is that, at such low voltages, there’s a low risk of shock or arcing.<br/><a href="http://blog.aimdynamics.com/the-right-ac-or-dc-current-sensor-for-measuring-power-consumption/">http://blog.aimdynamics.com/the-right-ac-or-dc-current-sensor-for-measuring-power-consumption/</a>Anonymoushttp://www.blogger.com/profile/15521429028153202875noreply@blogger.com0tag:blogger.com,1999:blog-6488330289911301834.post-62739783657479857522014-12-12T09:22:00.001-08:002014-12-12T09:22:04.066-08:00The 4-20 mA Current Loop Explained: How a DC Current Transformer Helps<img src='http://blog.aimdynamics.com/wp-content/uploads/dynamik-gen/theme/images/header_bg.png'/><br/>A simple 4-20 mA current loop consists of four parts: a DC power supply, a two-wire transmitter, a receiver resistor, and RWire. Unlike alternating current (AC), which changes all the time, direct current (DC) is consistent. Unless the loop uses a three-wire DC current transformer, the system may not recognize changes in current flow while in AC power. The three-wire variant can hold its own in a voltage drop. The amount of voltage lost is relative to the length of the wire; the longer the wire, the more voltage lost. According to the National Electric Code, voltage drops must be no more than 3 percent of circuit voltage from the breaker box.
