Tests of distance relay teleprotection schemes should check both relays simultaneously, including their communication link. This video shows a real test of a 110 kV overhead line. The protection was ...

OMICRON’s CPC 100 + CP CU1 helps to determine correct impedance values. The results of a false operation of a distance relay can be extremely severe. Non-operation may lead to damage or instability of ...

A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, allowing engineers to test protective relays under controlled conditions.

To simplify complex relay testing, the Megger Protective Relay Test Set (MPRT) provides built-in test routines, a touch-screen interface, and built-in transducer test capabilities. The unit displays ...

Interface relays connect computers and PLC logic devices to machines. But conventional block, modular terminal strips, and socket I/O relays are difficult to modify, and require hours of downtime for ...
