Checking for live stock

The Fluke 1555 insulation resistance tester is a high-capacity diagnostic instrument designed for evaluating insulation integrity on high-voltage equipment and electrical installations. With test voltages up to 10 kV and measurement capability up to 2 TΩ, it supports advanced preventive-maintenance routines on motors, switchgear, cables and transformers. The unit carries CAT III 1000 V and CAT IV 600 V safety ratings and is available with for traceable measurement confidence.

Technical Strengths and Measurement Range

  • Measures insulation resistance up to 2 TΩ for high-voltage electrical assets.
  • Output test voltages from 250 V to 10 kV for flexible insulation assessment.
  • Large LCD display with easy-to-read graphical feedback during long-duration tests.
  • Automatic polarisation index (PI) and dielectric absorption ratio (DAR) calculations.
  • ensures verified accuracy for compliance-driven maintenance routines.

Engineered for Maintenance and Reliability Teams

The Fluke 1555 offers stable, high-energy insulation testing for technicians who maintain large motors, long cable runs and critical power systems. Its broad test-voltage selection supports condition trending on equipment exposed to moisture, ageing or environmental stress. Long battery life enables extended field use, while onboard memory simplifies documentation and comparison of insulation values across service intervals.

Usage Scenarios of the Fluke 1555 LCD Insulation Resistance Tester

  • This instrument is widely used in power distribution, industrial manufacturing, utilities, and heavy equipment maintenance.
  • It supports commissioning tests, routine insulation checks, refurbishment projects and predictive-maintenance programs.
  • Typical applications include medium- and high-voltage motors, generators, switchgear, transformers and feeder circuits where insulation health directly influences equipment reliability and operational safety.
