The equipment adopts switching power supply to form high voltage constant current source, high voltage and stable current.
The bridge detection module and large screen display LCD are placed at high potential. The operating buttons on the panel are at ground potential and the bridge is operated by insulated rods.
Specially customized four-core high voltage measurement cable with shielding, copper mesh braided shielding layer reliable grounding, safe use. The four-terminal resistance measurement method avoids the error introduced by the lead resistance.
The high voltage constant current source and bridge are integrated in a portable drawbar plastic housing. High voltage, light weight, easy to operate.
Compared with the wave reflection method, the bridge method has no blind area, and is especially suitable for judging the breakdown point of short cables and near the end.
The high voltage and high current are especially suitable for the insulation and protective layer fault predetermined position of large length and large section high voltage complex cable system

Cable fault location intelligent bridge, set burn through and intelligent bridge in one. Burn through mode rated voltage 60kV, short circuit current 500mA, can quickly burn high resistance fault into low resistance. The rated working current of the intelligent bridge is 500mA, which greatly improves the fault location accuracy.
