Transformer capacity and noload tester is high precision instrument which is dedicated and designed for test of transformer capacity and loss parameters. Internal high efficient rechargeable battery can test 100 sets with full charged. In the meanwhile, amplify internal number combined 3-phase standard sine wave signal by power amplifier to provide 3-phase precise AC test power; no need to external connect power/voltage regulator/current booster and other tools, simplify wiring, improve working efficiency.  100% accuracy for capacity test, and can be used as two kinds of instrument: active transformer capacity tester and transformer loss tester. And It can test the capacity, noload current, noload loss, short-circuit loss, resistance voltage and so on.

• Precise measurement on transformer capacity, active test.

• Internal power, auto generate 3-phase big power test source.

• Test noload currnet/loss, short-circuit voltage/loss of al kinds of transformer.

• Auto calibration of wave distortion/temperature/voltage（noload test of non-rated voltage）/current（short-circuit test of non-rated current）, operator only key in cabliration factor based on transformer type to auto test the result after calibration. Applicable for big capacity transformer short-circuit test.

• Wide voltage circuit range, max test value is 750V and keep high precision.

• Percentage battery volume reminder and alert. 

• Big and high light LCD, kind interface.

• Micro-printer for test data printing.

• Auto test result storage, max storage 200 sets.
