Megger MFM10 Mobile Battery Operated Sheath Fault Location System (Up to ± 10 kV DC) - Optional AF
Description
The Megger MFM10 is a sheath fault location system for the testing, pre-location, and pinpointing of sheath faults. It is easy to use, precise, and fast. It works using the menu-supported 'Easy Go' test system, which is intuitive to operate, interprets the results, and requires minimal training. As such, the MFM10 can automatically test the cables and evaluate the measured data, giving you a fast, easy, and reliable tool to test the insulation of cable sheaths, and to pre-locate and pinpoint any detected faults.
Additionally, the bipolar pre-location feature supports the detection of galvanic and thermoelectric influences and increases the pre-location accuracy and quality. A multi-section facility permits the entry of cable segments with different parameters and difficult cable faults can be 'burned', thanks to the available high current of up to 750 mA. The MFM10 can also use its integrated protocolling feature with the approved Easyprot SW software to easily generate test reports.
