The new
Fluke 1555 insulation resistance tester 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 best in class, 3 year warranty and CAT IV 600 V safety rating. With measurement storage and PC interface, the 1555 is a perfect tool for preventative or predictive maintenance programs designed to identify potential equipment failures before they occur.
Applications
- Insulation resistance/leakage current measurement
- Step voltage testing
- Dielectric absorption ratio
- Polarization index
- Ramp voltage
For a 5kV model, see the
Fluke 1550C Insulation Resistance Tester.

The Fluke 1555's accuracy is specified for one year after calibration at operating temperatures of 0 °C to 35 °C. For operating temperatures outside the range (-20 °C to 0 °C and 35 °C to 50 °C), add ± .25 % per °C, except on the 20 % bands add ± 1 % per °C.
