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

The Fluke 1555 and redesigned Fluke 1550C insulation resistance testers enable users to conduct tests over a range of voltages with a three-year warranty and Cat IV 600V safety rating.

With their measurement storage and PC interface capabilities, they are the ideal tools for engineers, maintenance managers, industrial electricians, substation specialists and linemen using predictive and preventative 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 1,000V, then 100V steps thereafter.

A ramp function enables breakdown testing and timer settings of up to 99mins 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 unique, 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.

Flukeview Forms allows the user to document, store and analyse the readings, and present them in professional-looking documents.

The Fluke 1555 and Fluke 1550C feature a large digital/analogue LCD display for easy viewing.

They provide automatic calculation of Dielectric Absorption Ratio (DAR) and Polarisation Index (PI) without additional set-up.

They also offer capacitance and leakage current measurement, as well as resistance readings up to 2T ohms.

A guard system eliminates the effect of surface leakage current on high resistance measurements.

Kit versions are also available which offer an IP67 hard case, heavy duty alligator clips and a calibration certificate.

Fluke Calibration

Fluke Corporation was founded in 1948, specialising in electrical test and measurement products. Early in its history, Fluke recognised that the very best electrical metrology would be needed to support its products and undertook to develop this capability. From this activity, the calibration business was born. Over the years, many breakthrough calibration products were introduced, establishing Fluke as a leader in electrical metrology.

In 2000, Fluke acquired Wavetek Precision Measurement. In 2001, Fluke’s calibration business expanded into the temperature field with the acquisition of Hart Scientific and then into pressure and gas flow with the acquisition of DH Instruments (2007), followed by Ruska and Pressurements (2010).

The unified business’s unmatched breadth and depth in metrology puts Fluke Calibration in a unique position to deliver today’s and tomorrow’s calibrations solutions to customers who demand the very best, supported by an organisation they can count on for the long term.
