Megger DigiPHONE+ Cable Fault Pinpointer

Digiphone plus works off the “thunder and lightning principle” of fault location. In the same way you can measure how far away a storm is by counting the distant between a faster lightning flash and its slower thunder, this pinpointer works by measuring the energy around an underground fault. If you think of the flashover at a fault as the lightning, the Digiphone measures distance by figuring timing between that electromagnetic “flash” and the seismic (or acoustic) jolt also created at the moment of flashover.

Key Features:

• Finds the fault with unprecedented accuracy
