Insulation Oil Dielectric Strength Breakdown Voltage Tester


For testing Dielectric Strength of Transformer oil.

Insulating oil dielectric strength tester complies with astm d1816 astm d877 standard.

It is testing all kinds of Insulation Oil’s Dielectric Strength Value. Our company has three different types of single-cup oil bdv tester, three-cup oil bdv tester and six-cup oil bdv tester.


  • The instrument is controlled by a large capacity single chip microcomputer, and the work is stable and reliable.
  • There is a wide range watchdog circuit in the instrument to eliminate the phenomenon of death.
  • A variety of operation options, the instrument with astm d1816, astm d877 ,IEC156 three national standard methods and custom operation, can adapt to different users of a variety of choices;
  • An instrument using special glass mold for one time, prevent the occurrence of oil spills and other interference phenomenon;
  • The unique high voltage terminal sampling design of the instrument allows test values to directly enter the A/D converter, avoiding the errors caused by analog circuits, and making the measurement results more accurate.
  •  The instrument has the functions of over current, overvoltage, short circuit and so on, and has very strong anti-interference ability and good electromagnetic compatibility.
