Description

Overview

Megger, founded in 1889 in the UK, is the global gold standard in electrical test and measurement equipment. Born from the invention of the very first insulation resistance tester (the “Megger” name itself comes from “megohm” + “tester”), the company has spent over 135 years pioneering tools that ensure the safety, reliability, and performance of electrical power systems worldwide. Now headquartered in Dover, England, and part of the Viavi Solutions group, Megger operates manufacturing and R&D facilities in the UK, USA (Dallas & Valley Forge), Germany, and Sweden, serving utilities, contractors, railways, telecoms, mining, oil & gas, and industrial plants in more than 150 countries.

Key Aspects of Megger Quality

Megger’s reputation is built on extreme accuracy, legendary durability, and innovation that often becomes the industry benchmark.

• Unmatched Accuracy & Precision Megger insulation testers (from the iconic handheld MIT series to the flagship S1-1568 15 kV units) deliver stable, repeatable results even in noisy high-voltage environments, with patented guard technologies and dual-case designs that eliminate surface leakage errors. Their DLRO (Ductor) low-resistance ohmmeters and transformer test sets are routinely used as the reference standard during factory acceptance and commissioning.
• Built for the Real World Instruments are shockproof, dustproof, and waterproof (many rated IP54 or higher), with CAT IV 600 V / CAT III 1000 V safety ratings as standard. Technicians regularly report Megger tools surviving drops from ladders, years in dusty substations, or tropical humidity without drift or failure.
• Innovation Leadership Megger introduced the world’s first 18 V battery-powered 5 kV insulation tester (MIT525), first true 1-minute Polarization Index & Dielectric Discharge diagnostics, and now leads in smart assets with Baker AWA-IV static motor analyzers and cloud-connected PowerDB software for predictive maintenance. Recent models integrate Bluetooth, USB, and asset management apps that cut reporting time by up to 80%.
• Global Standards & Traceability Every instrument is factory-calibrated with certificates traceable to national standards (UKAS, NIST, PTB), and Megger maintains accredited calibration labs worldwide—critical for IEC 61850 substations, IEEE, and NETA compliance.
