FLC-908D EHV CABLE SHEATH FAULT PINPOINTER

1. GENERAL DESCRIPTION

    

1. GENERAL :

   FLC-908D  EHV cable sheath fault pin-pointer is an intelligent devices integrated with computer technology, digital signal processing technology and with innovative features, high-performance.

   It is mainly used for underground power cable (especially the single core high voltage cable) metal sheath grounding fault accurately pinpointing, also can be used in the auxiliary pinpointing of core grounding fault (in the case of sheath have been destroyed).The FLC-908D EHV cable sheath fault pin-pointer can measure the resistance current in the fault cable through the current sensor in the well, and locate the fault point of the cable in sections. For a large number of cables laid on cable bracket in cable tunnel, the fault point can also be determined by measuring DC voltage with high voltage probe rod.

   FLC-908D needs to be used in cooperation with FLC-900D/FLD-902D EHV cable sheath fault locator to complete the precise grounding fault pinpointing of EHV cable sheath.

2. FUNCTION FEATHER:

• Three pinpointing modes, suitable for different fault types:

  Step-voltage pinpointing mode: indicate the fault point directly and quickly find the fault point.

  Fault current pinpointing mode: Quickly find the fault point by measurement the resistance current in the fault cable.

  HV rod pinpointing mode: Measure the DC voltage in the fault cable to find the fault point.

• High sensitivity and wide response range.

• Digital signal processing technology, direct display signal waveform, strong anti-interference ability.

• Automatic zero adjustment, counteract the effect of ground potential change.

• Built-in large capacity lithium ion battery pack, under voltage automatic shutdown, long time no operation automatic shutdown.

  Solid case, light weight and portable.
