The three-phase four-wire high-leg connection is made by connecting the secondary windings of a three-phase transformer bank in delta or open delta and center tapping one of the transformer secondaries to provide a(n) ____ conductor.

Question

Quizplus · Accepted Answer

The high-leg connection requires a neutral conductor that is center tapped. This neutral conductor is used for grounding and provides a reference point for single-phase loads. The high-leg connection is sometimes called a "wild leg" or "stinger" connection because the voltage on the high-leg (or stinger) is higher than the voltage on the other two legs.
