Three major electric power trade groups in a letter on Feb. 15 urged the Department of Energy (DOE) to reconsider proposed energy efficiency conservation standards for distribution transformers, ...

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 ...

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 ...
