Datasheet

 

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.
 

Features:

  • Locates ground faults on floating battery systems
  • Operates on floating or resistance-grounded battery systems
  • Multiple fault detection and tracking
  • Automatic operation
  • Battery operated
  • Reads resistance directly (1 ohm to 100 kilohms)
  • Operates in the presence of surge-correction capacitors
  • Fused output leads for maximum user safety
  • Battery operated with internal automatic charger
  • Measures capacitance
  • Lightweight and portable
  • Tough polyethylene plastic sealed enclosure that provides high shock and vibration resistance
