Product Overview

Yuanxing Electronics’ Partial Discharge Current Sensors are high-frequency current transformers (HFCTs) designed for the non-invasive online monitoring of insulation in critical high-voltage assets. These precision partial discharge sensors detect transient currents emitted by PD activity within cables, GIS, and transformers. The PD sensor provides the high precision measurements needed for a predictive maintenance strategy by allowing for the early identification of faults before a failure occurs. The structures allow to improve the reliability and safety of power systems.
