The small, lightweight PTE-50-CE is the ideal instrument to test overcurrent and over/undervoltage protective relays, among many other applications. The reversible 100-VA amplifier can inject up to ...

Relays can be tiny elements, yet they play vital functions in electrical systems. They operate circuits, guard equipment, and ...

Megger is offering a series of seminars throughout Canada covering best practice for testing in substations. Megger is offering a series of seminars throughout Canada covering best practice for ...

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 ...

Omron has introduced 400V and 600V 110°C versions of its G3VM photo mos isolated electronic relay family, as well as a 40V 2Ω type in the 1.5 x 2.5 x 1.3mm 4pin VSON package. With G3VM-401xY2 and G3VM ...

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 ...

Testing verifies that protection schemes meet their intended purpose, ensuring safety and system integrity. Function testing involves manual or electrical manipulation of components to confirm signal ...

Pickering Electronics’ ultra-high-density reed relays have been named Passive or Electromechanical Product of the Year at the ...

Anyone who assumes that passive or electromechanical components are simple is either naive or inexperienced. Even a basic, functionally simple component such as a high-power, milliohm current-sense ...

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 ...
