Overview In the process of semi finished and finished production of power transformers, before the newly installed transformers are put into operation and according to the state Grid's preventive test rules, it is required to test the transformer's turn ratio or voltage ratio regularly.The traditional variable ratio bridge operation is tedious, the reading is not intuitive, and the necessary conversion, the test result is only one phase change ratio value.The transformer transformer ratio tester overcomes the shortcomings of the traditional transformer ratio bridge test, the screen uses a large screen high resolution LCD screen, convenient to use in the field, with Chinese menu prompt function, simple and intuitive operation, a complete three phase change ratio test, test speed, high accuracy. Technical parameter range 0.910000 The accuracy of reading 0.1 2 words or equal to 500 reading 0.2 2 words 500 3000 Reading 0.3 2 words 3000 The resolution of the 0.9 9.9999 0.0001 100 999.99 0.01 10000 and above 1 10 99.999 0.001 1000 9999.9 0.1 Working power supply AC220V 10 50Hz Instrument weight 3.5kg The use of temperature 10 50 Overall dimensions 260mm l 200mm W 160mmH Relative humidity 90 no dew Feature Full three phase sinusoidal inverter output, the output voltage is automatically adjusted, with soft start, soft stop function, so the test speed is fast, high precision Three-phase transformer, single-phase transformer, PT, Z type transformer ratio, group, polarity test function Blind test function, that is, variable ratio and group test when high and low pressure connection mode is not known; CT variable ratio polarity test function Angle difference test function for single-phase test Tap position can be tested up to 197
