The dielectric strength of transformer oil is also known as the breakdown voltage (BDV) of transformer oil. Breakdown voltage is measured by observing at what voltage, sparking strands between two electrodes immersed in the oil, separated by a specific gap.
PureTech HYYJ-501 Transformer Oil BDV Testing Kit (Oil Dielectric Tester) is developed according to the National standard GB-86 "Insulating Oil Dielectric Strength Determination Method" and International IEC/ASTM standards. The LCD display of this transformer oil testing kit can display the test process and test result, and the built-in EEPROM memory can store up to 100 groups of data. Test data and results, all human-computer interaction operations are completed by rotating the mouse, the micro-printer can print test results at any time, the tester is simple to operate, powerful, stable and reliable, strong anti-interference ability, no crashes during the test.
1) Screen and Printer for oil testing monitoring.
2) The test process fully complies with the requirements of multiple standards of IEC60156 and GB/T 507.
