Megger BGFT Battery Ground Fault Tracer

 

Megger Battery Ground-Fault Tracer is an economical, manually-balanced instrument that identifies, tracks and locates ground faults in ungrounded dc battery systems on-line. Megger BGFT is particularly effective in a high electrical noise environments, as the strength of the test current can be adjusted.

The Megger BGFT 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 Battery Ground Fault Tracer Features

  • The BGFT easily locates ground faults in underground DC systems
  • Operates in high electrical noise environment
  • The High / Low switch on the BGFT fault tracer provides the needed power to locate high impedance faults
  • Simplifies fault tracing by identifying fault characteristics magnitudes
  • Consists of a line-operated transmitter and a portable, battery-powered receiver
  • Bridge measurements of fault resistance and system capacitance
  • DIgital display of voltage and current signal amplitudes
  • Wide fault resistance measurement range from 1 kΩ to 399 kΩ
  • Immune to distributed noise
  • Soft-start charging system to prevent sensitive relay tripping
