BGFT Datasheet

The Battery Ground Fault Tracer is an economical, easy-to-use instrument that identifies, traces and locates ground faults in ungrounded dc systems— on-line. It is particularly effective in high electrical noise environments, as the strength of the test signal can be adjusted.

The Battery Ground Fault Tracer accelerates fault location by eliminating trial-and-error procedures and because faults can be located without going off-line. It is particularly useful in any industry where supply of power for operating measurement, communication and control equipment is critical.
Megger BGFT Features
  • Digital display of voltage and current signal amplitudes
  • Bridge measurement of fault resistance and system capacitance. (The use of the bridge is optional.)
  • Wide fault resistance measurement range from 1 kΩ to 399 kΩ
  • Immune to distributed noise
  • Soft-start charging system to prevent sensitive relay tripping
  • Convenient, hand-held receiver
  • Receiver gain control for optimal display resolution
