Localizers, suppressors, and experiments: Application of localizers of faulty feeders and an arcing ground suppressor to the system of the public service electric co., and descriptions of several experimental studies

The object of this paper is expressed briefly in the title. The localizer is a special type of relay which is connected to the current transformers of each feeder. When an accidental contact or arc occurs between one phase and ground on any feeder, the localizer of that feeder lights a signal lamp and sounds an alarm in the switchboard room.
