YN-HYG IEC Standard Transformer Oil BDV Tester
- The BDV test of transformer oil is a breakdown voltage test. Used to check the insulation strength of transformer oil. Dielectric strength refers to the maximum ability to withstand the voltage of the insulating oil. This test shows the insulation strength of the transformer oil.
- In the use of transformer oil, there are two main purposes, one is for insulation, and the other is to cool the transformer core and other Components. Therefore, when designing a transformer, the use of oil in the transformer depends on the rated voltage. Therefore, the oil should be tested according to the rated voltage.
- For the BDV test, place an oil sample from the transformer in a sample vial. When taking out the oil sample from the transformer, the sample bottle should be thoroughly rinsed with transformer oil, and the oil in the sample bottle should be properly drained to prevent moisture in the atmosphere from entering the sample oil.
- The transformer oil breakdown voltage tester manufactured by Yuneng oil purifier is a full self-reacting device, which is developed according to the requirements in International IEC-156 and International GB507-86 “Transformer Oil Dielectric Strength Mensuration”, combining the feedback opinions of all users.
- The instrument adopts a single chip as the leading part, and uses the method of “first setting and then testing”. The whole process is controlled by an automatic microcomputer. It is operated simply and used conveniently.
Features of Transformer Oil BDV Tester
- The instrument has the function of automatic detection. For example, after a startup, it enters a reset state to make the compressor governor reset.
- Tiny TPU-A panel printer is adopted for automatic printing out.
- Testing times, stirring and stationary time could be changed according to the requirements of users. Sound control and light control remind of continuous print and nonprint.
- This instrument adopts full automatic magnon for stirring to abate misproportion and air bubbles of oil samples.
