Megger BGFT Battery Ground Fault Tester
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.
