Product overview:

 

A split-core residual current transformer (RCT) is a type of current transformer designed for measuring residual or imbalance currents in electrical systems. It typically consists of two separate parts or halves that can be easily opened and closed around a conductor without the need to disconnect the circuit. This split-core design allows for convenient installation in existing electrical systems without the need for rewiring or interruption of power.

The primary function of a residual current transformer is to measure the difference between the current flowing in the live and neutral conductors of an electrical circuit. This difference, known as the residual or imbalance current, is crucial for detecting ground faults or leakage currents that may indicate a potential electrical fault. Split-core RCTs are commonly used in applications such as ground fault detection in power distribution systems, motor protection, and monitoring of electrical equipment to enhance safety and prevent damage.

The split-core design facilitates easy retrofitting into existing installations, making them a practical choice for various industrial, commercial, and residential applications where accurate measurement of residual currents is essential.
