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 ...

Be careful with single-phase motors, as most single-phase motors have components to help them start or continue to run ...

Ideally a test engineer would connect a separate instrument to each test point of a Device Undergoing Test (DUT), thereby providing the highest performance and most accurate measurements. But this is ...

Last month we discussed the basics of your car's 12-volt electrical system with the goal of understanding enough to trace problems to a particular electrical component. This month we're going to delve ...

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 reed relay was invented in 1936 by Bell Telephone Laboratories. Since that time, it has gradually evolved from very large, relatively crude parts to the small, ultra-reliable parts we have today.
