JY6611 Transformer Oil Breakdown Voltage (BDV) Tester Demo Video:

JY6611 transformer oil breakdown voltage tester (Oil Dielectric Strength tester,oil BDV tester) adopts completely new electromagnetic compatibility concept(EMC) which designed to avoid tester crash accident during testing, and also can still work well in high magnetic field.

JY6611 also use advanced  voltage breakdown control technology which will keep breakdown energy in a very low level,that will avoid pollution to oil sample during testing and make sure the test result are accurate and reliable.

1. Reliable testing processing:
With electromagnetism compatibility(EMC) to avoid tester crash in test process, so the oil breakdown voltage tester can work well in high-intensity electromagnetic environment,
2. 0 ~100kV  Stable and Precision Test Voltage:
With 0~100kV stable output and adopts completely new breakdown voltage control technology(RBM) to make the breakdown discharge energy to the lowest,which avoid oil sample pollution during test process and make test results reliable and accurate.Also JY6611 got ILAC.MAR Standard Calibration Certification.
3. New type oil cup:

JY6611 oil cup is made by new material with high strength and long service life to avoid fragile and leakage problem during testing.

4. Complete protection system:

JY6611 has a variety of  protection devices which will make sure the safety of operator and tester itself in accident like inferior oil breakdown voltage and empty cup breakdown.

5.Multiple international testing standards

Fully automatic test sequences for 12 common test standards around the world and spot tests (Standard:ASTM/BS/IEC/IRAM/AS/VDE)

6.International universal stainless steel calipers

Precise adjustment of standard electrode distances

7.Overall shielding technology

Perfect overall shielding technology can prevent all sources of electronic interference to ensure a pure test environment

8.Provide multilingual technical instructions

Provide English operation page and operation instructions in 15 languages
