The three-phase current transformer is employed for the protection of three-phase AC motors operating at 360V and 660V. It converts the AC current signal into a low-level AC voltage or current signal through a transformer, which is then transmitted precisely to microprocessor-based electronic circuits to safeguard the motor. This device is extensively applied in various settings for monitoring and protecting AC motors, air compressors, lighting, heating, and ventilation equipment; managing electrical energy; and in building automation systems. Due to their precision and stability, three-phase current transformers play an essential role in the power system, ensuring its safe and stable operation.
