The Stator Water-Cooled Generator Insulation Tester has strong load capacity, output rated negative high voltage of 2500V, short-circuit current of about 40mA; when load is 70kΩ, voltage drop is <10%. In addition to accurately measuring insulation performance, it can automatically measure temperature, humidity, and time; automatically calculate absorption ratio and polarization index; store each measurement result; comes with a built-in printer; and can communicate with a computer.
Main Features
Suitable for measuring insulation resistance, absorption ratio, and polarization index of water-cooled generators (fully automatic). ● The test rated voltage is 2500V, capable of measuring insulation resistance up to 100GΩ (100000MΩ).
● No need to compensate for water polarization potential. ● Even if the resistance between the frame and the water collecting pipe is as low as 3kΩ, measurement accuracy is guaranteed.
● When water resistance is greater than 80kΩ, test accuracy is guaranteed.
● Insulation resistance value is displayed simultaneously on an analog meter and a 3 LCD digital meter.
● Dual-scale automatic range conversion, logarithmic scale lines, easy reading.
● Displays output voltage and ambient temperature.
● Timer accumulates test time, displaying minutes and seconds.
● Use the [Rt] button to read instantaneous resistance value on the LCD digital meter.
● Automatically measures and memorizes R15S, R60S, R10min, R60S/R15S, R10min/R1min values.
● Comprehensive protection functions ensure operational safety.
