Ring Current Transformer

Product Details:

The Ring Current Transformer is a precision magnetic sensing component designed to measure AC current, detect leakage current, and monitor load conditions with high accuracy. Its closed-loop (ring-type) ferrite or silicon steel core ensures uniform magnetic flux distribution, resulting in excellent linearity and consistent performance across a wide current range.

This transformer is widely used in electronic energy meters, residual current devices (RCDs), current sensing circuits, and power monitoring systems. Its compact, ring-shaped design enables easy installation around conductors, providing non-intrusive current measurement without disturbing the main circuit.
