Model No :

Megger EZ-THUMP™ 12 kV, Model V2

Part Code :

Overview

The Megger's EZ-THUMP 12 kV model is a compact and lightweight, battery and AC line operated, portable cable fault location system. It is designed for quick, effective, accurate and safe fault locating operations to greatly reduce system customer outage minutes.Due to its portable and robust enclosure, it is ideally suited for all typical fault locating operations on MV cables.

Features

- TDR method to prelocate very low resistance cable faults, either phase to phase or phase to neutral, or by pair comparison
- Arc Reflection Method (ARM®) prelocation of high resistance flashover faults
- Single stage 500 Joule surge generator for pinpointing of high resistive faults up to 12kV
- DC testing for breakdown detection
- Insulation resistance measurement
- Sheath testing and sheath fault locating

Major Applications

- HV Testing (proof/insulation testing, sheath testing)
- Fault prelocation
- Pinpoint fault location
