6.3 Power Cable Sheath Grounding Current Online Condition Monitoring System

1. Product Overview

This system integrates online monitoring of cable circulating current and is applicable to single-core power cable circuits of 3 5 { k V } and above.

Under normal operating conditions,alternating current inside conductors induces an electromotive force on the metal sheath. Closed loops and sheath circulating currents willform if sheath insulation is broken,multi-point grounding appears,or the grounding system operates abnormally.
