Product Introduction
MOEORW-W5087C is a specialized monitoring unit for high-voltage cables and cable joints. It adopts high-frequency current transformer (HFCT) based on Rogowski coil principle to capture weak discharge pulses on grounding wires. With compact structure and high sensitivity, it is ideal for long-term on-line monitoring of cable insulation status.
