Megger BGFT Battery Ground Fault Tracer (246100B) identifies, tracks and easily locates ground faults in ungrounded DC battery systems on line. It simplifies fault tracing by identifying fault characteristic (resistive and capacitive) magnitudes. The BGFT is an economical, manually-balanced instrument that is particularly effective in high electrical noise environments, as the strength of the test current can be adjusted. The BGFT 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.
