Insulation testers go up to 10kV

Fluke has introduced two insulation resistance testers offering digital insulation testing up to 10kV for testing high voltage equipment including switchgear, motors, generators, transformers and cables.

The new Fluke 1555 and redesigned Fluke 1550C Insulation Resistance Testers enable users to conduct tests over a wide range of voltages using equipment with a CAT IV 600V safety rating. With their measurement storage and PC interface capabilities, they are suited to use with engineers, maintenance managers, industrial electricians, sub-station specialists and linemen using predictive and preventive maintenance programmes designed to identify potential equipment failures before they occur.

The Fluke 1550C Insulation Resistance Tester enables testing up to 5kV, while the Fluke 1555 tests up to 10kV. Test voltages are selectable in 50V steps from 250V to 1000V, then 100V steps thereafter. A ramp function enables breakdown testing, and timer settings of up to 99 minutes allow timed tests. A warning voltage function alerts the user that line voltage is present and gives the voltage reading up to 600V AC or DC for increased user safety.

Measurements can be stored in up to 99 memory locations. Each location is assigned a user-defined label for easy recall. An optical interface cable enables easy downloading to a PC running the FlukeView Forms software that is provided with the insulation tester.
