NRJJ-IIIInsulating Oil Breakdown Voltage Tester is used in electric power system petroleum chemical plant railways power plants factory of electrical equipment etc.;
It is mainly used for transformer oil capacitor oil electrical equipment insulated tools insulation materials electrical equipment factory to do power frequency withstand voltage test;
Voltage range: 0 ~ 80kV or 0 ~ 100kV.

(1) Special breakdown detection circuit on-line real-time breakdown monitoring ensure short-time breakdown rapid return to zero ensure that the breakdown time is less than 1ms avoid the carbonization of insulating oil or fiber formation; The cut-off current is less than 5mA and can be set arbitrarily from 1.0mA to 35mA; Ensure that the insulating oil is broken down for many times without crash and black screen;
(2) Adopt a micro-TPU-A panel printer to automatically print out test data at one time;
(3) Adopts automatic magnetic vibrator to stir to eliminate the unevenness and bubbles of the oil sample;
(4) Precise standard sine generator circuit transformation ratio and feedback monitoring circuit to ensure accurate measurement;
(5) Intelligent program control through three times of boosting three cups of samples can be tested in cycles which greatly shortens the test time and improves work efficiency;
(6) The oil cup is equipped with a built-in adjusting nut which can quickly simply and accurately adjust the distance between electrodes and facilitate calibration.
(7) During the test operation of the instrument if there is a sudden power failure or the three cups have not executed all the programs the computer will automatically record the tested data and suspend the execution of the set program until the power is turned on again and it will continue to run according to the program before the power failure.
