Definitions:

Open Delta

A transformer connection method using two transformers to form a delta configuration, typically used when one transformer of a three-phase system is out of service or for economy in a lightly loaded system.

Single-Phase Loads

Equipment that operates on a single alternating current (AC) power phase, usually seen in residential and light commercial settings.

High Leg

In electrical systems, a conductor within a delta configuration that carries higher voltage to ground than the other conductors.

Center Tapped Transformer

A transformer with a connection point (tap) in the middle of the secondary winding, which allows for splitting the output voltage into two parts, each half of the full voltage.
