Where are current transformers used?

Current transformers are widely used in many key links of power systems, and their main uses are as follows:

Measurement: Convert high current into standard low current (such as 5A or 1A) for use by ammeters, power meters and other instruments to achieve remote monitoring and data acquisition.

Protection: Cooperate with relay protection devices to detect overload, short circuit and other faults, quickly cut off the fault circuit, and ensure system safety.

Electric energy metering

Provide standardized current signals for electric meters to achieve accurate power calculation, suitable for industrial, commercial and residential electricity metering.

High insulation design realizes electrical isolation between the primary and secondary sides to ensure that maintenance does not affect the operation of the primary system, while preventing secondary equipment failures from affecting the high-voltage side.

Special scenario applications

Zero-sequence current detection: Used for ground fault protection, leakage or grounding problems are discovered in time by analyzing the zero-sequence current on the secondary side.

Inverter/motor control: Measure motor current, optimize operating status and protect equipment.

Configure 1-3 transformers according to demand, which are used for total current measurement, branch current monitoring or protection functions to improve the intelligence level of the distribution system.

Summary

Current transformers are indispensable core equipment in the power system, running through core functions such as measurement, protection, and metering. At the same time, isolation design ensures safe and reliable operation of the system.
