JUST LANDED: Megger MFM 10-1 Mobile Sheath Fault Location System

At Test & Measurement we endeavour to keep our hire fleet up-to-date with the current industry leading instruments and that’s why we are continuously adding new, innovative products to our extensive range of equipment. This week we are thrilled to introduce the Megger MFM 10-1 Mobile Sheath Fault Location System.

The Megger MFM 10-1 is a state-of-the-art mobile, battery operated sheath fault location system up to ± 10kV DC.

The instrument features an intuitive menu-driven operation, automatic measurement and evaluation system which enables cable sheaths to be tested and sheath faults to be pre-located and pinpointed as simply as possible. Data can be easily entered using the proven Megger rotary encoder principle which is made simpler with the 5.7” LED touch-screen.

The powerful 10kV DC source with positive and negative polarity allows HV cables to be tested while the bi-polar function ensures that external thermoelectric and galvanic influences are eliminated. A multi-section facility permits the entry of cable segments with different parameters. Difficult faults can be “burned” thanks to the available high current of up to 750 mA. The MFM 10-1 can also use its integrated protocolling feature with the approved Easyprot software to effortlessly generate comprehensive test reports.

The Megger MFM 10-1 Mobile Sheath Fault Location System is an excellent addition to your engineers’ cable testing instruments with its multi-functionality and extensive range of advanced features.
