Fault pre location is important when troubleshooting buried cables. This allows you to find the fault first before digging it up. Since you can’t see the cables, it would be a hassle to dig first and search for the fault. Thumpers are the tools used to find broken cables and chipped insulation. This electrical test equipment offers a simple way of detecting faults. What it does is send an electrical impulse and if it encounters a fault, an arc forms giving out an audible thump above the ground.
