Ground Fault Locator

Fluke GFL-1500

Ground Fault Locator

Quickly & safely locate ground faults in PV systems.

An innovative frontline troubleshooting set of tools to help technicians quickly pinpoint active ground faults in PV systems. It works by injecting a traceable signal into the array for fast, intuitive, non-contact tracing directly to the fault location.

  • Get PV arrays back online faster

  • Eliminate time-consuming brute-force troubleshooting

  • Decrease exposure to hazards with non-contract tracing

  • CAT III 1500 V DC / CAT IV 600 V rated transmitter & receiver
