Abstract: There is described a method and apparatus for supplying power to ancillary equipment comprising a prime mover cooled by a liquid pump to pressurize the liquid, first conduit means for the flow of fluid pressurized by the pump means to the ancillary equipment for actuation thereof and second conduit means for the return flow of liquid to one or both of the prime mover and the pump.

Abstract: A pad for supporting a transformer upon the earth's surface having an improved safety feature, the pad being formed of rigid material configured to rest upon the earth's surface and support a transformer and transformer housing on the upper surface thereof, the pad having a cable opening communicating between the top and bottom surfaces, and a hollow sleeve of rigid material, the sleeve being received in the pad cable opening and arranged such that the upper end of the sleeve extends above the pad top surface, the sleeve preventing objects inserted between the housing and the pad from engaging cables passing through the cable opening.

Abstract: A transformer unit comprising a transformer, a ground level base pad having a vertical cable opening therethrough, and an open top, open bottom vertical cable vault situated in the earth, the upper end thereof being received in the pad opening to provide easy access to and training room for underground electrical cables connected to the transformer.
