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.

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 ...

From generation to transmission and distribution, the power industry is changing. With distributed energy resources (DERs) increasingly participating in wholesale capacity, energy, and ancillary ...

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 ...

A utility can determine moisture content for steady-state conditions using a family of curves that show moisture content in the paper as a function of relative oil saturation, with temperature as a ...
