Megohmmeter - Wikipedia A Megohmmeter or insulation resistance tester, is a special type of ohmmeter used to measure the electrical resistance of insulators [1] Insulating components, for example cable jackets, must be tested for their insulation strength at the time of commissioning and as part of maintenance of high voltage electrical equipment and installations
Megohmmeter insulation testers | Fluke Megohmmeters, also known as insulation testers or “megger testers” measure resistance to determine current leakage and identify faulty insulation Fluke's digital insulation resistance testers provide reliable results whether you work on motors, generators, cables, or switchgear
Megohmmeter Working Principle | Megger . . . - Electrical Academia What is a Megohmmeter? The megohmmeter (or megger) is an instrument for measuring very high resistances, such as the insulation resistance of electrical cables A high voltage source is required to pass a measurable current through such resistances
How to Use a Megohmmeter: A Step-by-Step Guide - TRADESAFE A Megohmmeter is a device that measures the insulation resistance of electrical components, including wires, cables, motors, and transformers It works by applying a high DC voltage to the component and measuring the resulting current flow
