1500 Amp Peak Current Transformer System IN

The Current Transformer System consists of a 19-Inch Rack Mount Power Supply/Signal Conditioning unit, up to six CTs, and a 5- Meter Signal Cable for each CT. 

What is a Current Transformer?

Consisting of a closed core and windings, an electrical current transformer is a static device that can multiply or reduce alternating currents to protect and measure power systems, mostly high alternating currents.

Current Transformer Working Principle

What is the principle of a current transformer? Current transformers operate to convert large primary currents into small secondary currents based on the law of electromagnetic induction. The external voltage applied to the primary winding causes a magnetic circuit around the coil and perpendicular to the current. The output value of the voltage is obtained through the secondary winding attached to a voltmeter.
