A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, ...

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 ...

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 ...

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 ...

Power systems today operate in an environment where reliability and safety must be maintained despite rising loads, expanding ...

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 ...

Verification and diagnosis of complex switching operations in a test system has been made easier with the introduction of built-in self-testing capabilities to select models of Pickering Interfaces' ...

Fujitsu Components America, Inc. has introduced the DPST/DPDT 5-A PCB power relay series that meets glow-wire test requirements of the IEC/EN60335-1 standard for safe operation of consumer and ...
