The precision holding device PWD2000/P is used for the determination of the electric resistance per meter of power and medium voltage cables. The measurement is based on the 4-pole method according to Kelvin in order to eliminate the feed line resistances. The measuring current is supplied via hydraulic operated jaws, the measuring voltage picked up via spring-supported taps, with a distance between the taps of 1000 mm (+/- 0,1mm).
精密保持装置PWD 2000/P用于测量每米电力和中压电缆的电阻。为了消除馈线电阻，根据开尔文的四极法进行了测量。测量电流通过液压操作的嘴提供，测量电压通过弹簧支撑的水龙头获得，水龙头之间的距离为1000 mm(/-0，1mm)。
