An industry expert discusses use of the Weibull distribution for life testing electromechanical relays. Life tests for electro-mechanical relays can be set up using relatively small sample sizes, ...

A Relay Protection Tester is designed to simulate electrical quantities such as current, voltage, frequency, and phase, allowing engineers to test protective relays under controlled conditions.

Smaller, lighter and with a higher output power than any other comparable single-phase protective relay test instrument, Megger’s new SMRT1 smart protective relay test set is suited not only for ...

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, ...

Megger’s new SMRT 36 smart protective relay test set is suited not only for testing today’s installations and legacy plant, but also for meeting the future challenges associated with testing the smart ...

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 ...

DALLAS--(BUSINESS WIRE)--Smaller, lighter and with a higher output power than any other comparable three-phase instrument, Megger’s new SMRT 36 smart protective relay test set is ideally suited not ...

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 ...

Protective relay testing verifies that installed relays will trip correctly under real fault conditions, confirming settings, timing, and logic so protection schemes operate as intended during ...

Protective relays are critical power systems components, and it is essential to design and use them properly to detect power system issues. As NETA-certified technicians, we must be familiar with the ...
