Brea-down oil dielectric tester(BDV Tester) is a comprehensive index for insulating oil., which is special for testing insulating oil`s dielectric strength. ST Automatic dielectric strength oil tester is designed according to international standard of IEC156. Apply large integrate circuit, new type I/O interface, LCD displayer, and adopt industrial single chip as controller, which combined with special testing and anti-jamming technologies that greatly improve the tester`s performance.
- 1.Zero Start" and test chamber interlock provision.
- 2.Window panel for test observation.
- 3.80 KV & 100 KV test cells for ASTM & IEC standards.
- 4.Simple operation, automatically (can be finished just press on key).
- 5.Menu controlled. Input data can clear.
- 6.Can store 99 groups oil testing data which is convenient to reading and print.
- 7.The testing data can keep 100 years under the condition of power off.
- 8.System time can go on running under power off
Wtih auto test, auto handling, and auto print, and with high accuracy, easy operation and good safety.
The tester is applied to measure dielectric strength of insulation oil, test item being the instant voltage value of oil sample breakdown. The tester is a full auto oil-testing device, of high accuracy and photoelectric type, with a microprocessor served as the core component; The tester has successfully overcome the difficulty where strong electromagnetic field has a severe interference in microprocessor, making electromechanical integration possible.

Q: What is BDV test for distribution transformer?
A: When you say BDV you might mean the dielectric strength of transformer oil. A new transformer oil should have at lest a dielectric strength of 39 KV. from a British standard.Transformer oils used are normally tested using ASTM D877-82 with the KV strength tester using 1" electrodes spaced 0.1" apart and the test voltage increased at 3,000 volts/min until it breaks down. The average Kv obtained after 8 trials is considered the Oil dielectric strength.
Using this test method,dielectric strength at 30 kv and above is considered good. Dielectric strength between 23 to 29Kv is considered usable, but requires filtering. Below 23 kv, the transformer oil should be replaced. Another method ASTM D18747-82 uses the small radius electrodes but spaced only .o4 inches. The test voltage is 500volts/min and increased until breakdown. The dielectric strength is still the average Kv obtained in 8 trials. The dielectric strength of 28-29Kv is considered good. Below 28 kv, the transformer oil is usable but requires filtering. The latter method is considered a better test method.
