what is a CT Quiz Practice Quiz | Current…

Current Transformer — CT stands for Current Transformer, the device's primary function.

To measure high alternating currents. — CTs are primarily used to step down high AC currents to lower, safer levels for measurement or protection.

In series with the load. — The primary winding is in series to measure the current flowing through the circuit.

To connect to a measuring instrument or relay. — The secondary winding is connected to meters, protective relays or other measuring devices.

The core will saturate, and high voltage can develop at secondary. — An open secondary causes core saturation and dangerous high voltages.
