Keep Informed of Your Firm’s Power Usage with Split Core Transformers

This provides a variety of choices among the available split core transformers and other types from Aim Dynamics. In the past, experts would have chosen solid core transformers for their inexpensiveness and their accuracy. However, the problem with them is that they have to be put in place at installation; if you want to install a solid core current transformer afterwards, you’ll have to turn off the main power and be ready to pull out some wires. In contrast, a reliable split core current transformer would be able to be snapped on over a wire, with no need for screws or brackets. They can be added to an installation by placing control panels at important junctions in a system, so as to gather data. They aren’t as accurate as wound current transformers and have a higher price tag, but they are often the only options available for some situations like older facilities or the need for immediate power monitoring.
