When alternating current (AC) prevailed over direct current (DC) in the late 1800s, one of the deciding factors was the need for voltage levels to be raised and lowered throughout the power system to ...

A transformer transfers electrical energy from one system to another by induction. Except for grounding and bonding connections, there’s no physical connection between the two systems. For this reason ...

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 ...
