Fault location instruments, in the order you use them.
Grouped by the step they do, from the first pulse to the dig spot.

Step 1: Pre-location
Measure the distance to the fault.
A low-voltage pulse goes into the cable. The time its reflection takes to come back gives the distance to the fault.
Step 1, pre-locate
ARM Filter
Arc reflection filter
- Method
- Arc reflection (ARM)
- Works with
- TDR-901, PG-32
Step 2: Surge & conditioning
Break the fault down so it can be found.
A high-voltage surge breaks down high-resistance and intermittent faults, so they reflect clearly and flash over audibly.
Step 3: Pinpointing
Find the exact spot to dig.
Walk the route while the surge generator fires and listen for the discharge through the ground. The loudest point is where you dig.
Step 4: Route tracing
Follow the cable path.
A transmitter puts a signal on the cable and a receiver follows it, so the measured distance lands on the right street.
Step 4, trace route
