High leg delta systems--explanation and NEC requirements

WebHigh-leg delta (also called “red-leg” or “wild-leg” delta) configuration are commonly used in older three-phase electric power installations in which it supplies both line-to-line and line-to-neutral services in the same distibution system. Typically, it supplies lighting loads connected phase-to-neutral and 3-phase motor loads at line-to-line voltage. WebHigh Voltage: greater than 100 kV and equal to or less than 230 kV. Extra-High Voltage: greater than 230 kV but less than 1000 kV. Line-to-line voltages in three phase systems are typically 1.732 times the phase-to-neutral voltages: In symmetrical three-phase electrical system, the phase-to-neutral voltages should be equal if the load is balanced.
