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 ...
Electronic relays have evolved a lot since their introduction in the early '30s, but their basic purpose hasn't changed. Transistors and integrated circuits have replaced vacuum tubes and the term ...
