DC Ground Fault Locators

GAO’s DC ground fault locators are devices used to locate ground faults in DC electrical systems. A ground fault is an unintentional electrical connection between a conductor and ground, and can occur when an insulation failure or other fault allows current to flow from a DC circuit to ground.

 

GAO’s DC ground fault locators are composed of sensing device, monitoring device, current source, grounding test, and alarm system.

 

A DC ground fault locator is also known as DC ground fault detector, DC ground fault tracer, DC ground fault finder, ground fault locator for DC systems, DC earth fault locator, DC leakage current locator, DC insulation fault locator, DC ground fault tester, DC ground fault identifier, DC ground fault tracker, DC ground fault pinpointer, DC ground fault mapper, DC ground fault sniffer, DC ground fault detector and locator and DC ground fault isolation tool.
