An intact sheath of a plastic insulated medium voltage cable is the prerequisite for the avoidance of water ingress and subsequent cable faults. The MFM 5-1 is a universal test instrument for sheath testing including prelocation and pinpointing of location of a sheath fault. In the sheath testing mode, current measurements with 1 and 10 mA full defl ection can be carried out, permitting a detection of even minute insulation damage of the cable sheath. The instrument is very easy to use, being menu-driven. To get precise results of the fully automatic prelocation, only entering the total cable length is needed. The instrument will carry out a self-calibration, conduct a double measurement and display the result directly in metres.
