Fluke 1555 and
1550C Insulation
Resistance Testers
Technical Data
Digital insulation testing up to 10 kV, ideal
for wide range of high voltage applications
Evaluate the trends, eliminate the doubt
The Fluke 1555 and Fluke 1550C insulation resistance testers, offer
digital insulation testing up to 10kV, making them ideal for testing a
wide range of high voltage equipment including switchgear, motors,
generators and cables.
Fluke insulation testers can now conduct the entire range of test
voltages specified in IEEE 43-2000 with a best in class, 3 year
warranty and CAT IV 600 V safety rating. With measurement
storage and PC interface, the 1555 and 1550C are perfect tools for
preventative or predictive maintenance programs designed to identify
potential equipment failures before they occur.
Features include:
Test voltages to up 10 kV provides solutions for all applications
CAT III 1000 V, CAT IV 600 V safety rating
Warning function alerts the user that line voltage is present and
gives the voltage reading up to 600 V ac or dc for increased user
safety
Selectable test voltages in 50 V steps from 250 V to 1000 V, and
100 V steps above 1000 V
Measurements can be stored in up to 99 memory locations, with
each location assigned a unique, user defined, label for easy recall
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 T
Timer settings up to 99 minutes for timed tests
3-year warranty
Electrical specifications
The testers 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 35C to 50 C), add .25 % per C, except on the 20 % bands
add 1 % per C.
