Portable all-in-one fault locating system 6kV

The P4i is an easy to use all-in-one solution for troubleshooting, pre-locating and pinpointing of cable faults in complex LV, lighting and control cable networks. Menu guided computerised operation allows to detect and precisely locate various faults for even unexperienced users. Featuring a large colour screen, the P4i can display measurement curves, test results and message codes simultaneously. This complete system includes a precise DC HV test facility that measures and displays leakage current over time. Integrated full scale TDR capability in combination with the high voltage

arc reflection mode (ARTi) will isolate and pre-locate low as well as high resistance faults with utmost precision. As a result precise pinpointing will take much less time. The fast HV surge pulse cycles of 3 sec. with up to 1000 Joule energy support the most demanding locating jobs while the multi-dimensional safety system ensures maximum safety for instrument and operator. The optional pinpointer Kamphone and Locator S are used for flash-over faults or cable sheath faults respectively. As an economic alternative, the version P4e is available without integrated TDR and ARTi.
