Megger Overhead Line Testing System

Overview

The Megger Overhead Line Testing System (from the Seba Dynatronic range) is a reflectometry-based instrument for locating faults and impedance irregularities on de-energised overhead transmission and distribution lines. By sending a pulse along the line and analysing the reflections, it identifies major faults such as breaks, short circuits and branch-offs, as well as smaller changes in impedance caused by poor connections, faulty insulators or in-growing trees.

With a measurement range up to 1000 km, a high real sampling rate and a large 15-inch colour display, the system gives line crews clear, detailed reflectograms for fast fault location over long distances. Its rugged IP54 housing and wide operating-temperature range make it suitable for demanding field conditions, while on-board storage keeps records for later analysis.
