Electrical power industry is using current transformers in metering, protective relaying.

It eases the flow of huge amount of currents, in the presence of high voltages in the circuit in a consistent manner.

Current transformers works on the principle of flow of current in the secondary circuit which is perpendicular to the volume of current flowing in its primary circuit. It is primarily a device to measure the current and check the functioning of power grid.

Use of current transformer is such that it cut offs securely to measure and manage a circuitry from the high voltage available on the circuit. You can control the current transformer by passing a single primary turn under a well-insulated toroidal core with great amount of turns of wire wrapped. Current transformer also can be used to accurately measure the flow of current and identify, monitor the operation power usage. The current transformer is basically defined by its value of current ratio flowing from primary to secondary circuit.
