Fluke 1550C 5kV Insulation Tester

The completely redesigned Fluke 1550C provides unparalleled digital testing of insulation up to 5kV, making it the ideal choice for everything from simple spot checks to timed and breakdown testing of a wide range of electronic equipment including switchgear, motors, generators, and cables. With the Fluke 1550C insulation tester, you can now carry out tests up to 5kV as specified in IEEE 43-2000. FEATURES Test voltages to up 5kV and save time by trending on the spot only with Fluke Connect™. CAT III 1000 V, CAT IV 600 V safety rating. Warning function alerts the user that line voltage is present. Selectable test voltages in 50 V steps from 250V to 1000V, and 100V steps above 1000V. Measurements can be stored in up to 99 memory locations. Long battery life gives the user over 750 tests between charges. Automatic calculation of Dielectric Absorption (DAR) and Polarization Index (PI) with no additional setup. Guard system eliminates the effect of surface leakage current on high-resistance measurements. Large digital/analog LCD for easy viewing. Capacitance and leakage current measurement. Ramp function for breakdown testing. Resistance measurements up to 2 TΩ. Timer settings up to 99 minutes for timed tests. Fluke 1550C Specifications Electrical Specifications The tester's accuracy is specified for one year after calibration at operating temperatures of 0°C to 35°C. For operating temperatures outside the range (-20°C to 0°C and 35°C to 50°C), add + .25% per °C, except on the 20% bands add + 1% per °C.
