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, ...

If you're a casual track and field fan, you've probably heard of the 4x100 and 4x400 meter relays and can likely deduce how they are run from the names of the events alone. However, those are not the ...

Insulation resistance testers, often called megohmmeters, are fundamental tools for preventive maintenance, used to assess the integrity of insulation in motors, cables, transformers, and other ...
