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.
