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.
Filtration is the process of separating suspended solid matter from a liquid, by causing the latter to pass through the pores of some substance, called a filter. The liquid which has passed through the filter is called the filtrate.The filter may be paper, cloth, cotton-wool, asbestos, slag-or glass-wool, unglazed earthenware, sand, or other porous material. Filtration is very frequently employed in chemical technology, and it often presents great difficulties.r the filtrate may be drawn upwards through the filter, which is suspended in the liquid to be filtered; thus clogging does not occur so easily, as a large part of the precipitate settles to the bottom of the vessel and does not come in contact with the filter until most of the liquid has been drawn off.
