Fault Detection Systems
Fast fault location and residual current monitoring for MV cable networks and overhead lines.
The Challenge
In medium voltage distribution networks, locating a fault after a trip can take field crews hours — causing extended outages and increasing operational costs. Fault passage indicators and residual current monitors dramatically reduce fault location time by identifying which cable section carried the fault current. Selecting the right technology — whether for cable or overhead line, whether with local indication or remote SCADA reporting — requires understanding network topology, fault current levels and communication infrastructure.
Our Approach
We assess your network type — underground cable, overhead line or mixed — to determine the appropriate fault indicator technology.
We evaluate fault current levels and grounding regime (isolated neutral, compensated or solidly earthed) to select the correct detection algorithm.
We advise on local versus remote indication and communication options — GPRS, IEC 61850, Modbus — for SCADA integration.
We provide fault indicators from Orion EE and equivalent manufacturers, covering both cable clamp and overhead line clip-on types.
We support your network planning team with placement recommendations and detection threshold guidance.
