For ungrounded systems, the greatest voltage between the given conductor and any other circuit conductor is also the phase-to-ground voltage. On a 480V, three-phase, 3-wire, ungrounded delta system, the phase-to-phase voltage is 480V. Based on the definition, this is also the phase-to-ground voltage for this system.
Welted definition, a ridge or wale on the surface of the body, as from a blow of a stick or whip. See more.
