The Battery Ground-Fault Locator (BGL) simplifies the tracking of ground faults on floating dc-powered control systems.
It features automatic operation, can be used on live battery systems and has the unique capability of detecting, tracking and locating multiple faults on a battery system without having to resort to sectionalizing.
This is accomplished by injecting a low- amplitude 25 Hertz test signal on either the positive or negative side of the power bus and tracking the signal with one of several available clamp-on sensor probes.
A fault simulator also is provided with the instrument, allowing the periodic verification of the resistance and capacitance ranges of the BGL.
