Fluke 1537 5kV Insulation Tester 2 Teraohm Range CAT IV 600V for Industrial Motors

The Fluke 1537 is the top model of the 1500 insulation tester series. With test voltages up to 5 kV and a 2 TΩ measuring range it reaches medium voltage motors, generator windings and long feeder cables that 1 kV testers cannot polarise properly, while the guided test sequence keeps field procedures repeatable.

• New 1500 series platform with programmable test voltages from 250 V to 5 kV
• Extended 2 TΩ range for medium voltage machines and long cable runs
• Automated PI, DAR and ramp test routines with pass or fail indication
• Live circuit detection and automatic discharge for safer testing

• Test voltages of 250 V, 500 V, 1000 V, 2500 V and 5000 V
• Insulation resistance measurement up to 2 TΩ
• Polarisation index, dielectric absorption ratio and step voltage tests
• Timed tests up to 99 minutes with automatic result storage
• CAT IV 600 V rating and rugged carry case for site conditions

Specifications are typical values for the standard version. Accessory sets and calibration options are quoted per project.

• Commissioning tests on medium voltage motors and generators
• Transformer winding insulation assessment
• Long feeder and busbar insulation testing before energisation
• Annual predictive maintenance trending for critical assets

Delivered in a rugged carry case with high voltage test leads, guard lead, alligator clips, charger and calibration certificate. We support fleet standardisation programmes and can supply yearly calibration and firmware update services with the instrument.
