1. Application
Digital insulation resistance meter is also called as megohmmeter, high voltage insulation resistance tester, etc. This economic instrument has a large LCD screen gray backlit display, data storage, data access, alarm, automatic shutdown and other functions. At the same time, it also has the function of measuring AC voltage absorption ratio and polarization index of DC voltage. The machine is beautiful and upscale, has a wide range, high resolution, convenient operation, easy to carry, accurate, reliable, stable performance, strong anti-interference ability.
Moreover, this megger multifunction tester has a shockproof, dustproof, moisture-proof structure and becomes a commonly used and indispensable instrument for telecommunications, electricity, meteorology, computer rooms, oil fields, electromechanical installation and maintenance, and industrial enterprises that use electricity as industrial power or energy. It is suitable for measuring the resistance value of various insulating materials and the insulation resistance of transformers, motors, cables and electrical equipment.
2. Why Insulation Resistance is Required?
An insulation resistance (IR) test measures the total resistance between any two points separated by electrical insulation. The test, therefore, determines how effective the dielectric (insulation) is in resisting the flow of electrical current. Such tests are useful for checking the quality of insulation, not only when a product is first manufactured but also over time as the product is used.
Performing such tests at regular time intervals can detect impending insulation failures before they occur and prevent user accidents or costly product repairs.
Whether you work on motors, generators, cables, or switch gear, the FUOOTECH DMG Series digital insulation resistance testers provide noise-free, reliable results. With advanced performance, a FUOOTECH DMG Series insulation resistance tester is designed to be safe, simple to use and gimmick-free. A megohmmeter test for insulation troubleshooting, commissioning, and preventative maintenance applications.
