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 ...

The cost of component failures continues to increase as electronic products become more complex. Most component replacement costs are associated with marginal devices that become intermittent or fail ...
