The Fluke 1555 Megohmmeter/Insulation Resistance Tester, 10kV, > 2 TΩ offers digital insulation testing up to 10 kV, making it ideal for testing a wide range of high voltage equipment, including switchgear, motors, generators and cables.
Fluke insulation testers can now conduct the entire range of test voltages specified in IEEE 43-2000 with a CAT IV 600 V safety rating. With measurement storage and a PC interface, the 1555 is a perfect tool for preventative or predictive maintenance programs designed to identify potential equipment failures before they occur.
