Megger M-THUMP-5-1000 Portable LV Cable Fault Location System

Model:
Megger M-THUMP-5

Portable LV Cable Fault Location System

The M-Thump5 Portable Cable Fault Locating System provides safe, efficient, and extremely easy-to-use solutions for quickly identifying, pre-locating, and pinpointing various types of cable faults in low and some medium voltage power cables. The M-Thump5 was developed to meet the requirements for typical low and lower medium voltage distribution cable fault location markets. The unit features a light weight aluminium enclosure, equipped with handles as a portable unit, or as a permanently installed vehicle mount unit.

Description

Circuit parameters include:

  • Circuit voltage up to 6.6 kV 
  • Insulation EPR, XLPE, PVC, and PILC
  • Typical conductor sizes between #2 and 500 MCM (34 mm2 to 250 mm2 )
  • Typical circuit lengths from a few hundred feet (100 m) up to 3 miles (17000 ft or 5000 m)

Typical end users include: operations department of power utility companies, electrical departments within municipalities including street light maintenance, private network operators, high voltage electrical contractors, service companies, port authorities, mining, airports, military bases, petrochemical and paper companies. The M-Thump 5 unit incorporates Megger’s “E-Tray” technology, a concept that has been already proven in other products (EZ- Thump, EZ-Restore Overdrive, SMART-Thump, and TDR T3090) and which will be carried forward into future Megger products. The E-Tray adds the unique capability to access and operate every function through an innovative and intuitive user interface, without the need to make adjustments and the software suggesting the next procedural step.

FEATURES AND BENEFITS

  • “Quick-Steps” menu is especially convenient where operators may not be called upon to use the equipment on a regular basis
  • “Expert Mode” provides up to 20 individual TDR features to the experienced user for optimum fault locating results
  • Customer configurable menus for the TDR function
  • DC testing up to 5 kV with indication of insulation resistance
  • Burning/fault conditioning up to 1 kV max current 500 mA and up to 5 kV 70 mA
  • Pre-location methods: TDR with phase comparison, ARM with multishot, ARM burn, ARM with multishot, ICE (surge pulse)
  • Pinpointing Methods: Surging/thumping up to 5 kV, Voltage gradient at 1 kV/500 mA or at 1-5 kV/70 mA
  • Heavy-duty lightweight aluminium enclosure.
  • Safe-op check protects user from incorrect or faulty and ground connections (F-Ohm)
  • E-Tray interface eliminates lengthy training

APPLICATIONS

M-Thump5 represents a new generation of advanced underground cable fault locating systems that require less training than a traditional thumper-only system. It is the only fault locator with built-in intelligence to interpret the results of the initial test sequence. The “turn & click” rotary button operation lets the user automatically proof test, pre-locate, pinpoint and sheath test the fault from one convenient control panel. No adjustments are required, unless the operator chooses otherwise. The M-Thump5 features an automatic safety check to protect the user from incorrect or faulty ground and return connections (F-Ohm)
