The FLD-903P digital step voltage pinpointing device is a high capacity device integrated computer technology and digital signal processing technology.
It is used to pinpoint metallic sheath grounding fault of the underground power cable, special the single-core HV cable.
It is also used to assistant pinpoint the core-grounding fault when the sheath is broken.
It could also be used to test the fault cable resistive current by current transducer to section fault locating.
Matched with FLC-900D HV signal source, FLD-903P could be used to pinpoint the EHV cable sheath grounding fault.
