NRJJ-II Transformer Oil Withstand Voltage Tester also known as Insulating Oil BDV Tester it is developed on the base of the requirements of international standard IEC-156 and GB507-86 " Insulating liquids - Determination of the breakdown voltage at power frequency Test method " and also combined with the views of the majority of user’s feedback.
The LCD can display the test process and results the built-in EEPROM memory can save up to 100 sets of test data and results all the interactive operation is completed by rotating mouse micro printer can print the test data and test result the instrument has the advantages of simple operation powerful function stable and reliable strong anti-interference ability no crash phenomenon occurred during the test..


Characteristics and functions
This instrument is applied to test a variety of insulating oil dielectric strength. Its main characteristic as follows:
● The instrument is equipped with the automatic detection function. For example it will automatically enter into the state of reset and the voltage regulator will be back to zero when the instrument is power on.
● The use of the miniature TPU-A panel printer automatic printing output.
● It can change the number of test the time of stirring and standing voice control and light control to remind continuous printing and non-printing.
● This instrument adopts completely automatic magnetism oscillator stirring eliminate the oil sample uneven and air bubbles.
