MFM 5-1: Sheath Testing, Prelocating and Pinpointing

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 pre-location and pinpointing of location of a sheath fault. In the sheath testing mode, current measurements with 1 and 10 mA full deflection 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 pre-location, 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.

Features

• Sheath testing, fault pre-location and pinpointing combined in one unit. (Pinpoint receiver ESG 80-2 not included in scope of delivery)
• Sheath test up to 5 kV with or without timer
• Time saving pre-location of sheath fault
• Automatic pre-location with self-calibration and second measurement for confirmation
• Clear indication of pre-located distance in meters
• Reduction of thermal load by using pre-location, limited current and pulsed pinpointing signal
