Technical Specification: MM G 5


Introduction
The Sheath Tester MMG 5 is mainly designed for withstanding voltage testing of cable sheaths made of PE or PVC as well as for the location of sheath faults
on shield plastic-insulated cables and the detection of earth-leakage faults in plastic-sheathed cables.

In conjunction with Sheath Fault Pre-location Device
MVG 5, sheath faults can be pre-located.

The following measurements can be taken with the
MVG 5:
  • Sheath fault pre- location on shielded medium-high voltage cables
  • Pre-location of line-earth faults on plastic-insulated low-voltage cables.
Pin-Pointing is carried out by means of the Line-To-
Earth Fault Locating Device ESG 80-2 using the method of measuring the step voltage.

Due to the excellent burn down effect achieved by the
full-wave rectification, this device is very well suited for converting high-resistance cable faults in low-voltage power cables into low-resistance ones.

Moreover our new Sheath Tester MMG 5 has further special features such as:
  • Continuously adjustable output voltage in
    voltage ranges 500 V1000 V,2,000 V and
    5,000 V
  • Protection against overload by voltage and
    current control
  • Fault location at reduced power to prevent damages to adjacent wires or cables
  • Indication of voltage and current by two analog indicating systems
  • Automatic discharge unit provides for removal
    of residual charge and for earthing the test
    object
  • Clock-controlled operation of the voltage source to prevent the drying-out of faults when pinpointing sheath faults
  • Excellent burn down effect through full-wave rectification
