In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

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 ...

Last month's Code Calculations article covered transformer calculation definitions and some specifics of delta transformer calculations. This month we turn our attention to the differences between ...

AutomationDirect’s line of power products now includes Acme Electric’s dry-type encapsulated 3-phase transformers. The NEMA 3R transformers are excellent for dust or lint-laden atmospheres and are ...

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 ...
