ABSTRACT:
A device for detecting electrical faults internal of a liquid and gas containing power transformer. Portions of two electrically nonconducting chambers are immersed in, and each chamber has an opening into, said liquid. One of said openings permits the relatively free passage of liquid through same and the other opening contains a liquid-immersed flow-restricting orifice. A sudden change in internal transformer pressure, indicative of an internal transformer fault, creates a pressure differential between chambers because of the liquid-immersed flow-restricting orifice associated with one of said chambers and the viscous properties of said liquid. This internal failure indicating pressure differential is sensed by a suitable differential pressure sensor which, in turn, actuates power transformer fault, indicating means.
