10KV Insulation Resistance Meter for water -cooled generator
I.Brief introduction
HM2020 water cooled insulation resistance tester is mainly used for insulation resistance test in laboratory or on site. It's built in high precision microcurrent measurement system and digital booster system. Just need to connect tested object by a HV cable and signal cable to make measurement . It make test automatically , display tested result with big LCD screen, and store the test results accordingly .
Hot tags : water cooled insulation resistance tester, water cooled insulation resistance tester
II.Main features 1. 32-bit micro-controller, English user interface, easy to operate. 2.Output current, (2500V, the output is greater than 25mA), short-circuit currents greater than 25mA. 3.The high voltage generating module adopts fully closed technology,built in protection resistance, safe and reliable. 4.With strong anti-interference ability, it can meet the field operation of uHV substation. 5.Automatic discharge after testing and real-time monitoring of discharge process.
Suitable for measuring the insulation resistance, absorption ratio (R60S/R15S) and polarization index (R10min/R1min) of the water-cooled generator.
The measured HV voltage is 2500V.
7.The water polarization potential is automatically compensated and adjusted, even the resistance between the engine base and water collecting pipe less than 10kΩ, it can also ensure accuracy of measurement . 8. With high output power,load resistance between lines and sinks can be as low as 100kΩ,2500V insulation resistance tester can measure as low as 1 m Ω (2500 v). 9. The insulation resistance is indicated by an analog progress bar. The testing process of capacitive test can be observed visually without delay,Logarithmic scale and indicating value run out small, convenient to read . 10.Digital display adopt 3 1/2 LCD digital table. 11.The LCD timer display the test time,and show its minutes, seconds at 0 ~ 32 minutes cycle, the bee beeps every 15 seconds. 12.R15S, R60S, R10min, absorption ratio and polarization index can be automatically measured and memorized for checking and reading when the test is completed. 13. It can compensate and adjust water polarization potential automatically.
III.Main technical performance 1. Accuracy:±(5%+5 digits) Measure range:0.1M~200GΩ 2. Double display:Digital and analog progress bars 3. Temperature measurement:-25ºC~125ºC 4. Range of testing voltage :2.5KV 5. Short circuit current:>=25mA Measure time:1min.~10min(related to measurement way ) 6. Charge power supply:180~270VAC ,50Hz/60Hz±1% (powered by mains power or generator ) 7. Working environment:temperature -10~40ºC, humidity 20~80% IV . Factory release test cargo delivery
