What is a Current Transformer?

A current Transformer is a device that is surrounded by a live phase wire in a three-phase system, to measure the current flowing through it.

In electrical engineering, a Current Transformers (CT) together with Potential Transformers (PT) is called an Instrument transformer.

Transformers are constructed so that their characteristics match the application for which they are intended. The differences in construction may

AC type protective relays are actuated by the current and voltage supplied by the current and potential (voltage) transformers which

Current Transformer: For Selection, Operation, and Inspection & Maintenance In general, large currents (hundreds of amperes) cannot be directly input

Why is transformer flux constant? When a load is connected to a transformer current (say I2) flows through secondary coil
