Transformers - Bushing Potential Device


The General Electric Type KA-108 Bushing Potential Device is a reliable, safe, economical voltage transforming device for the operation of instruments and relays from high-voltage circuits, 115 kV and above.


The KA-108 bushing potential device is well suited to operate the usual types of relays, synchroscopes, voltmeters, indicating lamps, wattmeters (not for revenue) and similar instruments requiring a potential source of essentially constant ratio and phase relation with respect to the high-voltage circuit. The device's major field of application is in protecting and control equipment for generating plants, substations, transmission lines, etc.

Features and Benefits

  • Economical
  • High-flexibility
  • Adjustable to a variety of HV bushings
  • Constant burden capacity
  • Rugged construction
