Home / Relay protection test lead
Flexible banana test leads with shrouded plugs are recom-mended for operator safety. To avoid high voltage shock hazard, external CT circuits must NOT be open circuited. Megger's smart relay testing solutions and expert support help you validate protection performance, improve system reliability, and ensure continuity of power across your network. Its powerful six current sources (three-phase mode: up to 64 A / 860 VA per channel) with a great dynamic range, make the unit capable of testing even high-burden electromechanical relays with very. Power System protection is crucial part of power station and substations safety which use protection relays and circuit breakers to isolate faulty parts or zones within the plant including Generator zone, Motor zone, Feeder zone, Bus zone, Transformer zone and Transmission Lines zone. Compact, powerful relay test systems for carrying out highly complex tests with ease and precision.
Flexible banana test leads with shrouded plugs are recommended for operator safety. 2.5mm2 multi-strand wire with PVC insulation is recommended for adequate current rating and flexibility.
