WebDec 25, 2014 · Floating (no ground reference) Delta is often found on ships, they use detectors and monitors rather than traditional fuses to handle faults to the hull ("ground"). For several reasons, they don't want a ground short to pass excess current through certain parts of the hull, nor stop the motors during critical maneuvers in high seas. WebHigh-leg delta (also known as wild-leg, stinger leg, bastard leg, high-leg, orange-leg, red-leg, dog-leg delta) is a type of electrical service connection for three-phase electric power installations. It is used when both single and three-phase power is desired to be supplied from a three phase transformer (or transformer bank).
