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 ...

With its ease of configuration and its comprehensive range of facilities, including a variable-frequency voltage source with a continuous phase-shift function, Megger’s new self-contained SVERKER 780 ...

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 ...

Production test of a finished electronic product often involves two techniques: in-circuit test (ICT) and functional component test (FCT). The ICT technique examines a non-powered circuit board to ...

An experienced protection and integration engineer can help determine the best configurable relay settings to provide maximum system protection and advanced functionality. Photo courtesy: Emerson ...

RF coaxial SPDT relays address signal-routing applications that demand a combination of high frequency, high power, and excellent RF performance. What role does an SPDT relay play in test applications ...

Last column, I wrote about various applications where fire alarm relays could be used to integrate a commercial fire alarm system with other electrical systems at a customer’s site to provide them ...
