Relay protection CT disconnection detailed explanation
CT disconnection refers to the occurrence of circuit disconnection in the secondary circuit of the current transformer (CT), which will make the secondary side unable to transmit current signals normally to the relay protection device or measuring instrument. The main function of the current transformer is to reduce the large current in the high-voltage line to a safe level in a certain proportion to facilitate the measurement and protection of the equipment to work.
