10KV Insulation Resistance Tester , For Large Transformers,
Generators, High-voltage Motors Test
I. Product Introduction :
Insulation resistance tester, also known as megohmmeter, is used
for testing insulation resistance. UT515A tester has LCD
large-screen backlight display, data storage, data review, alarm,
automatic shutdown and other functions. At the same time, it also
has the function of measuring AC/DC voltage absorption ratio and
polarization index. The whole machine has wide measuring range,
high resolution, easy operation, convenient carrying, accurate,
reliable, stable performance and strong anti-interference ability.
Moreover, it has anti-vibration, dust-proof and moisture-proof
structure. It is an indispensable measuring instrument for telecom,
electric power, meteorology, computer room, oil field,
electromechanical installation and maintenance, and industrial
enterprise departments that use electricity as industrial power or
energy. Rugged, reliable and easy to use, the user's work is more
effective.
UT515A testers can measure insulation resistance of large
transformers, generators, high-voltage motors and more. it can also
measure PI, DAR and AC/DC hipot functions. Measured data can then
be analyzed through PC software. UT515A can produce test voltage up
to 10kV on insulation resistance measurement. AC voltage for hipot
test is up to 750V, DC voltage for hipot test is up to 1000V,
II. Main Features :
1. Support insulation test from 0.01MΩ to 1000GΩ;
2. Integrated 6 voltage levels, 250V, 500V, 1000V, 2500V, 5000V,
10kV;
