Introduction AC transformer ratio tester is an innovative product are mainly applied to change than group test transformer, PT and CT polarity test, test speed, high accuracy. Technical Indicators Working power supply AC22050/60 HZ Instrument weight 3.8 kg Instrument dimension 325 mm L 225 mm W 125 mm H Use of temperature -10 50 Relative humidity 90 No dew Functional Characteristics It has the function of blind measurement, that is, to perform variable ratio and group test when there is no connection between high and low voltage. Based on the test of conventional transformer, Z-type transformer and PT sample, the polarity test function of CT variable ratio is added, and the application field is wider Wide range and high accuracy, the variable ratio measurement range can reach 10,000, and the test accuracy can be guaranteed 0.3% when the maximum value is 10,000. It has perfect protection functions such as reverse connection protection and output short circuit protection.
