When using an open delta with a center tapped transformer, one wire is the high leg. The high leg is the one that _____.
A) has the highest voltage
B) has the lowest voltage
C) has the most amperage
D) is mounted highest on the panel

Question

Quizplus · Accepted Answer

In an open delta with a center tapped transformer, the high leg is the one that has the highest voltage relative to the neutral or ground. This is due to the way the transformer windings are connected in an open delta configuration, leading to one of the phases having a higher voltage potential.
