Megger MMG 10 Cable Sheath Tester

The MEGGER PIL 8-Cable and Phase Identifier, paired with the robust sheath test system MMG 10, represents a formidable solution in the cable testing and maintenance field. The MMG 10 is specifically designed for the voltage testing of plastic insulated cable jackets. It effectively evaluates leakage current relative to the lengths of the cables, ensuring comprehensive testing coverage.

One of the standout features of the MMG 10 system is its adjustable current limiter. This crucial component prevents the potential drying out or unintended alteration of a fault spot during tests, safeguarding the integrity of the cable throughout the procedure. This feature is particularly important when dealing with delicate or critical cable systems where maintaining the original condition post-testing is paramount.

In addition to safety features, the MMG 10 excels in fault resolution. It can generate a high output current suitable for the low-resistive burning of faults. This capability is essential for effectively dealing with hard-to-detect faults that require precise and powerful intervention.

For pinpoint accuracy in identifying sheath faults in plastic insulated shielded cables and earth faults in unshielded cables, the MMG 10 employs a pulsed output voltage. This method enhances the detection process, making it more efficient and accurate. The pinpointing of these faults is performed using the step voltage method, facilitated by the Earth Fault Locator ESG 80-2 / ESG NT. This sophisticated approach allows for precise localization of faults, minimizing the time and effort required in troubleshooting and repairs.
