Megger M-THUMP5 Portable LV Cable Fault Location System

Megger M-THUMP5 Portable LV Cable Fault Location System — All-in-One Fault Finding

The Megger M-THUMP5 is a compact, portable cable fault location system for low-to-medium voltage cables up to 6.6 kV that combines every stage of fault finding — pre-location, pinpointing, proof testing and fault conditioning — in a single rugged unit. Delivering 1000 J of surge energy at 5 kV and a bright sunlight-readable display, it lets utility and industrial teams locate cable faults quickly and accurately in the field.

The Megger M-THUMP5 is for utility operations, municipal street-lighting teams, HV contractors, ports, mines, airports and industrial plants who locate faults on low-to-medium voltage cables up to 6.6 kV. It packs nine identification, prelocation and pinpointing methods behind Megger’s E-TRAY interface, which walks less experienced users through proof test, prelocate and pinpoint with yes/no prompts, while expert mode opens the full TDR toolset.

From Megger’s M-Thump datasheet (M-Thump_DS_V04) and brochure:

• Surge: single-stage 1000 J at up to 5 kV; proof test 0–5 kV DC with insulation-resistance readout
• Burn: up to 500 mA at 0–1 kV and 70 mA at 1–5 kV; ARM, Burn ARM and ICE prelocation to 5 kV with Multishot
• TDR: range to 160,000 ft / 52 km with on-screen multi-phase comparison
• Pinpoint: surging plus voltage-gradient sheath/earth fault mode; F-Ohm safety check on ground/return connections
• Build: 7 in HiBrite 1280 × 800 display, IP53 (top open), 51 kg, 635 × 457 × 812 mm, 230 V 50/60 Hz with isolation transformer, -20 to +50 °C

Megger M-THUMP5 Key Features

What the Megger M-THUMP5 packs into one aluminium case:

• High surge energy — 1000 J single-stage output at 5 kV for effective thumping and pinpointing of faults on low-to-medium voltage cables.
• Multiple pre-location methods — TDR with phase comparison, Arc Reflection Method (ARM®) with multishot, and ICE surge-pulse reflection.
• Long TDR range — pre-locates faults on cable runs up to 52 km (160,000 ft).
• Proof & burn testing — 0–5 kV DC continuous proof test with two-stage burning (500 mA at 0–1 kV, 70 mA at 1–5 kV) for fault conditioning.
• Sheath fault & insulation testing — built-in sheath fault testing and insulation-resistance readout.
• Sunlight-readable display — 7-inch HiBrite TFT colour display at 1280 × 800 for clear outdoor use.
• Field-ready build — heavy-duty aluminium enclosure with handles, IP53 (top open), −20 °C to +50 °C operation.
• Mains powered — 230 V, 50/60 Hz with internal isolation transformer.

Megger M-THUMP5 Applications

The M-THUMP5 is ideal for utilities, contractors and industrial teams locating faults on low-to-medium voltage distribution and service cables — from pre-location and fault conditioning to pinpointing and proof testing — in a single portable system suited to on-site and vehicle-based use.

What comes with the Megger M-THUMP5

What comes with a typical M-THUMP5 portable unit:

• Megger M-THUMP5 portable LV cable fault location system
• Hardwired HV and safety-ground leads (25 ft / 7.6 m standard; 50 ft / 15 m optional)
• 1.8 m mains lead set (US, Schuko or UK) and instruction manual. Order a compatible termination kit separately (1015-526-AOC outside North America). Pinpointing needs an ESG-NT2 or digiPHONE+2.

Megger M-THUMP5 FAQ

What fault-location crews ask about the M-THUMP5:

• Which cables can it work on? Megger lists EPR, XLPE, PVC and PILC, single- or multi-core, armoured or shielded, typically a few hundred metres up to about 5 km.
• Is training heavy? E-TRAY guides the sequence automatically. All E-TRAY products share the same HV turn-on interlock, so crews who know one unit can run another.
• Do I get a pinpointer in the box? No. Megger requires an ESG-NT2 or digiPHONE+2 for acoustic/electromagnetic pinpointing.
• Portable or vehicle mount? Both: aluminium case with side handles, or permanent vehicle mounting.
