5kV insulation resistance tester

Supplier News

FLUKE has introduced a new 5kV insulation resistance tester. The Fluke 1550B MegOhmMeter combines insulation resistance testing up to 5000V with measurement storage and PC interface software.

The 1550B is designed for industrial electricians, plant maintenance personnel, utility technicians and anyone who installs, repairs or maintains switchgear, motors, generators or cables. It features standard test voltages starting at 250V, new programmable test voltages available in 50 volt steps from 250V to 1000V and 100 volt steps from 1000V to 5000V. It also offers automatic calculation of dielectric absorption and polarisation index with no setup and an improved ramp function from 0Vdc to 5000Vdc for breakdown testing. Measurement storage is provided in 99 memory locations, each assignable with a user defined, four character, alpha-numeric label for easy recall. Results can be downloaded to a Windows-based computer using the Quicklink 1550B software and optical interface cable that come with the meter.

The meter provides insulation resistance testing up to one TΩ, with five standard output voltages: 250V, 500V, 1000V, 2500V and 5000V. The Fluke 1550B's warning voltage alerts notify the user that voltage is present and give the voltage reading up to 600Vac or dc. With its large, fast-responding analogue/digital display, the Fluke 1550B shows measurement changes graphically with analogue bar graphs as well as digital measurements. The last-reading memory display is ideal for insulation resistance and low ohms readings.

It is powered by a high-capacity, rechargeable 12-volt battery that provides enough energy for up to 2,500 tests. In addition, the meter is fully tested to comply with EN 61010-1, CAT III 600V over voltage rating, EN 61557 installation testing and EN 61326 EMI immunity.

The 1550B comes with a waterproof soft case for tester and accessories, heavy-duty test leads, 5000V-rated probes, alligator clips, interface adapter and cable, Quicklink 1550B PC Software, user's manual, quick reference guide, line cord and a 12-volt, rechargeable battery. Quicklink 1550B software requires a computer running Windows 95, 98, ME, NT 4.0, 2000 or XP. It comes with a standard two-year warranty.
