Insulation Resistance Testers Above 2.5kV [1.8MB PDF]
A guide to diagnostic insulation testing above 1 kVWHY A 10 KV INSULATION TESTER?
Megger invented insulation testing before the beginning of the 20th century and has continued to lead the market in innovation and technological advancement. So, why did we develop a 10 kV model when all other suppliers stopped at 5 kV? The answer is in the IEEE standards. Megger developed a 10 kV unit to meet the new testing recommendations outlined by the IEEE. Megger has offered a 10 kV insulation resistance tester since 2001.
The Complete Guide to Electrical Insulation TestingWHAT IS “GOOD” INSULATION?
Every electric wire in your plant – whether it’s in a motor, generator, cable, switch, transformer, etc. – is carefully covered with some form of electrical insulation. The wire itself is usually copper or aluminum, which is known to be a good conductor of the electric current that powers your equipment. The insulation must be just the opposite from a conductor: it should resist current and keep the current in its path along the conductor.
