What is a Current Transformer?
A current transformer (CT) is an essential electrical device used to measure alternating current (AC) by producing a reduced current proportional to the actual current in the circuit. It is widely used in power monitoring, metering, and protection systems. CTs come in various types, including 5a current transformers, which provide a standard secondary current output for compatibility with measuring instruments. These transformers enhance safety by isolating measuring instruments from high-voltage circuits.Features of Current Transformer
