The main application scenarios of 0.66kV low-voltage current transformers include current measurement, energy metering and relay protection. This type of transformer is usually used in indoor AC circuits and is suitable for power systems with a rated voltage of 0.66kV and below and a wide range of rated currents (ranging from 5A to 4000A).
Application scenarios
Current measurement: 0.66kV low-voltage current transformers can be used to measure the current in the circuit to help users understand the load of the circuit.
Energy metering: By measuring the current, the transformer can calculate the amount of electric energy used, which is suitable for occasions that require accurate metering.
Relay protection: In the power system, the transformer, as part of the relay protection device, can quickly cut off the power supply when the circuit is overloaded or short-circuited to protect equipment and personal safety.
