ART Automatic Transformer Turns Ratio Tester

ART Transformer Automatic Turns Ratio Tester, with the features of three-phase test, rapid test speed, simple to operate, perfect protection function, good anti-seismic ability and portable, widely used to measure a variety of single-phase transformers, three-phase transformer, the turns ratio of the PT, terminal group and polar, etc.

(1) Single-phase power input, internally generated three-phase power output, better equivalence, it solved the problem of groups misjudgment caused by the common single-phase power output-type devices.

(2) Just takes a few seconds to complete three-phase test. It only need input one standard turns ratio when measure multi- gears transformer, all the turns ratio error of tap can be calculated.

(3) If reverse connection of the high side and the low side, the instrument will automatically cut off the output power and sent an alarm signal; there is a fuse on the high side against output short circuit or overload.

(4) Do not need to select the transformer wiring, no need to input standards transformation turns ratio, measures Y / *, */ Y transformer needn’t external shorted , it can automatically test.

(5) It can upgrades in the field needn’t disassemble through the built-in online JTAG programming interface.

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.
