Adopt 32-bit micro-controller control, all Chinese operation interface, easy to operate.
Output Current, (under 2500V output more than 25mA) , short-circuit current, J25MA.
The high-voltage generator module adopts the full-enclosed technology, has the protection resistance inside, is safe and reliable.
Strong anti-interference ability, can meet the field operation of EHV Substation.
The automatic discharge is tested, and the discharge process is monitored in real time.
It is suitable for measuring insulation resistance, absorption ratio -LRB-RR15sR15S) and polarization indR10MIN0R1min1min) of water-cooled generator.
The test high voltage is 2500V.
The water polarization potential is compensated and adjusted automatically.The resistance between the base and the catchment is as small as 10K Ω to ensure the accuracy of the measurement.
High output power, the load resistance between the lines can be as low as 100 kΩ (2500V) insulation resistance measurement is as low as 1 MΩ (2500V).
The insulation resistance value is indicated by analog progress bar, which can directly observe the test process of capacitive test piece without delay. Logarithmic scale, indicating the value of small jump, easy to read.
Digital display using 31/2 LCD digital table.
LCD timer display test time, and 0-32 minutes cycle to display its minutes, seconds. The buzzer beeps every 15 seconds.
R15s, R60s, R10min, absorption ratio and polarization index can be automatically measured and memorized for checking and reading when the test is finished.
It has the function of compensating and adjusting water polarization potential automatically.
