DC Current Transducer Products: New, Upgraded Hall Effect Technology

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.

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.

Analog vs. Digital Sensors

There are many different types of sensors 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.

Analog sensors

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.

Real-Time Data from a Current Transformer

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.

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.

Flexible Current Transformers: Better Energy Efficiency with eGauge

Energy monitoring can lead to energy savings. This, in turn, can lead to benefits for the bottom line and the environment. Flexible current transformer suppliers like Aim Dynamics can provide you with the energy monitoring tools you need to track your electricity consumption. One of the company’s most revered products, the eGauge, can help you identify, plan, and execute energy-saving measures in a systematic way. What is the eGauge? The eGauge is a stand-alone product that can reduce the power usage of a commercial or residential property. It can be integrated with certain systems if you want to take your energy savings to the next level.

The Right AC or DC Current Sensor for Measuring Power Consumption

A current of five amps is common in power adaptors for laptops, which also usually operate at 12 volts. 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.

The 4-20 mA Current Loop Explained: How a DC Current Transformer Helps

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. Otherwise, operators risk pushing an appliance to its breaking point due to lack of current.

Split-Core Transformers: Common Features

Modern split-core transformers are easily installed, easily connectable devices that can be attached to virtually all types of wiring terminals. Preferably, a split-core transformer is attached to electrical wiring by snapping the device around the conductor. High quality split-core transformers—such as those produced by Magnelab—have the highest standards in terms of interleaving joints and self-locking mechanism. Typically, these products have a rated accuracy of +- 1 percent between 10 and 130 percent of their graded input.

Best Practices: Taking Measurements with a Sound DC Current Sensor

Whether your equipment just finished a measurement earlier this morning or it is fresh out of the box, always assume that there is something wrong with it. Carefully inspect your equipment for any loose wires, worn-down insulation, etc. As they say, it’s better to be safe than sorry. In the event that you do find something wrong with your equipment, you’ll need to buy a replacement. Whether you need new DC or replacement AC current sensors, or any other type of equipment, make sure you only deal with reputable suppliers like Aim Dynamics. A trusted supplier will have a vast selection of equipment that is sure to suit your needs.

Adapting a New Flexible Current Transformer in a Data Center’s Grid

A data center is one of the prime assets a medium or large company may have. However, something’s amiss when part of its machinery breaks down and compromises your information as a result. Part of the power solutions may include erecting a new flexible current transformer set-up with support from a company such as Aim Dynamics. Flexible current transformers or FCT are fundamentally the same as split-core current transformers in the sense that they do not have to physically tap directly inside a circuit. The most prominent feature of an FCT is that the Rogowski coils are soft – making them easier to install in areas with little room – and they are wrapped in colored linings.

Using a Quality Split Core Current Transformer for Submetering Work

In an age of environmental consciousness, it’s easy to overlook the consequences of leaving the power on all day even when nobody’s home. As such, you must act to curtail the unnecessary power usage and figure out where savings are possible. Installing a sturdy split core current transformer (CT) like those sold by Aim Dynamics can be a step in that direction. Split-core CTs are small devices designed to measure the current flow of a primary conduit without having to rewire. The device’s centerpiece is a magnetic core wrapped with thousands of secondary windings. The output is typically a low current or low voltage. Mounting harnesses are sometimes set up after attaching the transformer over the conducting wire. However, most units work perfectly fine by simply dangling from the primary conductor.

An Energy-Efficient Future with Split-Core CTs

Split-core current transformers (CTs), among other things, are used to conduct electrical load surveys. Offices and factories periodically ask for a thorough assessment of their energy consumption and ways to get more for less. Such an assessment answers the question: "How much energy does it take the load to convert electricity to light, heat, or motion?"
