Fluke 1555
Insulation Resistance Tester Test Insulation at up to 10kV Plus Polarization Index Test
The Fluke 1555 10kV Insulation Resistance Tester offers six pre-set test voltage levels at 250V, 500V, 1000V, 2500V, 5kV & 10kV or specific programmable test voltages can be chosen between 250V to 10kV. To help find breakdown voltages a ramp test function is also available here the voltage ramps up 100V per second until it reaches a specific voltage or until a sudden drop in measure resistance is detected and stored to memory. The tester also performs two other important tests the ‘Polarization Index’ test (commonly known as the PI test) and ‘Dielectric Absorption Ration’ test (commonly known as the DAR test).
What we like:
It’s the range of both the insulation test voltage up to 10kV and the high insulation resistance measurement up to 2TΩ. Then on the physical side you have a strong robust instrument supplied in an impressively strong carry case, it’s that sort of total package that could take a bit of passing around between power generating engineers (you know what I mean) without getting worried that it’s not going to come back in one piece. Of course it also safely covers all of the test requirements expected of a professional 10kV insulation resistance tester including PI and DAR tests.
