The Fault Wizard is designed to thump through multiple transformers on a de-energized circuit where a fault has occurred. You may thump from the open point, switchgear, or an overhead riser. Since the Fault Wizard will give you the distance to the fault location, you will be able to quickly identify and isolate the faulted cable between two transformers, thus restoring service quickly. After the cable has been isolated, the Hi-Pot Mode can be used to test the isolated cable to confirm (before re-closure) that the cable contains the fault. Even though the Fault Wizard is compact and lightweight it still delivers almost as large a pulse of energy as many thumpers associated with TDR systems. The discharge delivered at the cable fault can be heard above ground with common listening devices used by the electrical utility industry and heard quite often with just your own ears. This gives the Fault Wizard a stand-alone capability when pinpointing the location of a fault after the faults general location has been determined. The Cycle Mode of operation allows repeated thumping (every six seconds at full voltage) for pinpointing the fault.
