Current transformers can perform circuit control, measure current for power measurement and control, and perform roles for safety protection and current limiting. They can also cause circuit events to ...

Tucson, Ariz. — C&D Technologies has introduced a new series of current sensing transformers designed to measure and monitor AC currents. Combining an isolation voltage of 500 Vdc and a primary ...

Monitoring the current taken by a mains-powered appliance can be a challenge, particularly if the application demands an inexpensive solution that must provide galvanic isolation for user safety.

All electrical installations, devices and machines rely on the quality of electrical insulation. A failure of insulation usually leads to a failure of the system in which it is used, often with ...

While consuming less electricity than their older, less efficient counterparts, high-efficiency motors are much more likely to trip their respective circuit protectors when they start. Initial ...

Whenever a power or distribution transformer is isolated from the power system, it is probable that residual magnetism remains in the core due to the phase shift. However, residual magnetism also ...

Inrush current effect is common in electric motors. Sometimes, in case of ill-designed electrical wiring systems, switching on the motor may activate the fuse. It is caused by the inrush current – ...

As the primary switching device used in a broad range of power conversion applications, MOSFETs play a central role in power supply design. Defining their performance characteristics is crucial to ...
