The sheath fault location system with bi-polar

measuring voltage method – easy, precise and fast

• Testing, prelocation and pinpointing of sheath faults
• Voltage up to ±10 kV DC
• High current of up to 750 mA
• Only one HV connection cable
• Automatic measurement and protocolling

Description

The intuitive menu-driven operation of the MFM 10

with fully automatic measurement and evaluation

enables the testing of cable sheaths as well as the

prelocation and pinpointing of cable sheath faults

in the most simple way possible.

The entry of data is done according to the wellproven

SebaKMT rotary encoder principle and is

supported by a touch screen.

The very powerful 10 kV DC source with positive and

negative polarity allows the testing of HV cables.

The bi-polar function ensures the elimination of

external thermoelectric and galvanic influences.

A multi-section facility permits the entry of cable

segments with different parameters.

The available high current of up to 750 mA enables

also the “burning” of difficult cable faults.

Integrated protocolling feature in combination with

the approved Easyprot Software for an easy and

reliable test generation.
