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

Complex grids depend on equipment such as transformers, protection relays, switchgear, and cables—each of which can develop faults not immediately visible during normal operation. As a result, ...

May 20, 2009, UK -- Protective relay installations that are based on IEC 61850, the new international communication standard for electricity substations, can now be tested easily and conveniently with ...

Pickering Interfaces (Clacton-on-Sea, UK) has introduced the PI-MXT90-100 test tool that identifies faulty relays on its complex PXI switching matrices. The diagnostic tool uses a test adaptor and a ...

Insulation resistance testers, often called megohmmeters, are fundamental tools for preventive maintenance, used to assess ...

The objective of protective relays and protective schemes is to protect electrical equipment such as transformers, lines, cables, bus bars, etc. during abnormal system conditions. Hence, protective ...

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' ...

Pickering Interfaces is lowering the cost of ownership of switching systems with the introduction of its eBIRST diagnostic test tools. The eBIRST tools, designed specifically for Pickering Interfaces’ ...

Complying with reliability standards requires considerable resource planning. The tools and suggestions provided here may help engineers conform to new generator relay loadability requirements. But ...

Relays are electromechanical devices that use a magnetic solenoid to actual a switch. When current is passed through the solenoid coil, it produces a magnetic field. The magnetic field is strengthened ...

Testing a circuit breaker is about judging reliability under fault conditions, not just checking continuity or voltage. A ...
