HPRW-2690C Water-cooled Generator Insulation Characteristics Test Set/Tester
General information
Specially used to test water-cooled generator, HPRW-2690C series can test directly without blow-dry water coolant and eliminate the influence of polarization potential automatically, so as to meet the latest national standards for product verification. The output current is up to 50mA, and output voltage is max.5000V. It includes high-precision micro-current measurement, digital voltage boost and polarization potential compensation system.
Feature
Microcomputer controlled, LCD screen, LV shield measurement.
Automatic measuring R15, R60, R600 and automatically calculating absorption ratio and polarization index.
Test voltage is negative HV 5000V/2500V, with strong loading ability. When the resistance(water resistance) between winding and water collecting pipe is lower than 120kΩ/70kΩ, test voltage drop <10%.
Measuring range 0-200GΩ(5000V); 0-100GΩ(2500V)automatic switching ranges.
Automatic compensation and eliminate the test result influence caused by water polarization potential. Even the resistance between water collecting pipe and engine base is lower at 3kΩ, the measurement accuracy can be ensured.
The analog bar pointer is combined with the digital display to show the changing trend of the data and the accurate measurement results.
Display test time and the buzzer will sound every 15s automatically.
Discharge HV automatically after measurement. Discharge time is no more than 5s.
Automatic measuring environmental temperature, air humidity and date/time of every test.
Save up to 60groups of measurement results.
With RS232 port, easy to communicate with PC.
With printer.
With comprehensive and perfect protection functions and high working reliability.
