Fluke Insulation Tester, 250 V Min, 10 kV Max, 2 TΩ Insulation Resistance, CAT IV 600V, CAT III 1V FLUKE 1555

Fluke FLUKE 1555 Insulation Tester is a robust handheld instrument designed for comprehensive insulation integrity testing on high-voltage electrical equipment. It supports selectable test voltages from 250 V up to 10,000 V, enabling thorough dielectric assessment across diverse industrial applications. The 2 TΩ insulation resistance capability facilitates detection of extremely high resistance values, critical for maintenance and commissioning tasks.

This model integrates a rechargeable lead acid battery (Yuasa NP2.8-12) providing extended field operation with a typical battery life of 750 tests per charge. Safety compliance with CAT IV 600 V and CAT III 1 V ratings ensures protection when testing at high distribution installation points. The LCD screen, paired with an analog bar graph, delivers clear numeric results and visual trend analysis.

Operating temperature supports a range from -20°C to 50°C, allowing usage in demanding environments including outdoor sites with controlled humidity tolerance. The device features wireless connectivity via an infrared-to-wireless adapter enabling mobile app integration for remote start/stop, trending, and cloud data storage.

Applications include preventative maintenance on medium- and high-voltage motors, condition assessment of power cable insulation, commissioning and troubleshooting switchgear assemblies, generator insulation verification, and predictive maintenance with historical trending data capabilities.

Safety features include live-circuit voltage detection up to 600 V AC/DC with warnings to prevent testing on energized circuits. Test modes cover ramp and timed polarization index (PI)/dielectric absorption ratio (DAR) tests, capacitance, and leakage current measurements to diagnose insulation deterioration due to moisture, contamination, or degradation.

The kit includes test cables with crocodile clips, an infrared USB adapter, AC power cord, the fitted 12 V lead acid battery, FlukeView Forms Basic Software, and a user manual on CD.

This insulation tester is ideal for industrial, laboratory, construction, and power generation environments requiring accurate, safe, and efficient insulation testing and diagnostics.
