Semi-Automatic Oil Breakdown Voltage Tester


PE-SOBDV-100 is a semi-automatic transformer oil breakdown voltage testing kit. The kit is a highly precise and accurate instrument which can perform both breakdown voltage test as well as proof (withstand) test.

Semi-automatic Oil Breakdown Voltage tester is is  designed as the middle range product lies between fully automatic  and  manual  BDV for the customers who accepts  the fully automated features with some limitation.

The Oil BDV test kit can operate with any one prefix standard  loaded as per customer requirement.

This test gives final results as per standard  test procedure and the result will display after completion. This result will remain till unit is powered. Also customer can use this Oil BDV test kit in Manual mode and can select stand time, intermediate time, stirring time , HV on as per own accord(Custom Test ).
