NR3630 is designed for the insulation test of water-cooled generator, also can be used to make insulation test of other material in the laboratory or field. The output current is more than 20mA, the maximum output voltage is 2500V. It contains high-precision micro-current measurement systems and digital booster system. Only need to use a high-voltage wire and a signal line to connect the tested object to realize the measurement. The measurement is carried out automatically, and the results are displayed by the large screen LCD, and the results can be stored.
Overview
● It is controlled by 32-bit micro-controller full English user interface easy to operate.
● Automatically calculate the absorption ratio and polarization index and automatically store each minute of data of 15 seconds 1 minute 2 minutes or 10 minutes to facilitate the analysis.
● Output current (2500V the output is greater than 25mA) short-circuit currents greater than 40mA.
● Fully enclosed high voltage generation module technology internal protection resistors safe and reliable.
● Perfect anti-interference ability can meet EHV substation on-site operation.
● Automatic discharge after testing is completed and real-time monitoring of the discharge process.
