Digital Insulation Testing up to 10kV
The 1555 and the 1550C insulation testers offer digital insulation testing up to 10kV, making them 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 600V safety rating. With measurement storage and PC interface, the 1555 and 1550C are perfect tools for preventive or predictive maintenance programs designed to identify potential equipment failures before they occur.

• Test voltages up to 10kV provides solutions for all applications.
• CAT III 1000V, CAT IV 600V safety ratings.
• Voltage breakdown detection alerts the user that voltage is present and gives the voltage reading up to 600V AC or DC for increased safety.
• Selectable test voltages in 50V steps from 250V to 1000V and 100V steps above 1000V.
• Measurements can be stored in up to 99 memory locations, with each location assigned a unique user defined label for easy recall.

• Long battery life gives the user 750 tests between charges.
• Automatic calculation of Dielectric Absorption (DAR) and Polarization Index (PI) with no additional setup.
• Guard system eliminates the effect of surface leakage current on high-resistance measurements.
• Large digital/analog easy to view LCD.
• Capacitance and leakage current measurements.
• Ramp function for breakdown testing.
• Resistance testing up to 2TΩ.
• Timer settings up to 99 minutes for timed tests.
• Three-year Warranty.
