XGDZ-08 High resistance fault locater is designed based on the MURRAY theory.It suits to locate the breakdown point(low resistance,high resistance,flashover breakdown)and much lower insulation resistance without breakdown point of a variety of buried wire and cable.Of course,it is also used to locate defect point of a variety of cable in the cable factory.
- XGDZ-08High resistance fault locater(high voltage bridge method)includes a high frequency and high voltage constant-current source,which makes the amplification of bridge sensitivity don't interfered by power,makes power and bridge into one.Cable being measured is a special high voltage cable.Introducing the principle of four-terminal resistance measurement makes location precise.Bridge placed on high voltage side and operating button safely grounded completely solve the limitations of high resistance location,make bridge method no blind spots,accurate,convenient and so on.
