Product Description Automatic three-phase TTR Transformer Turn Ratio MeterOverviewTRANSFORMER TURN RATIO TESTER is applied to measure the voltage ratio of three or single phase transformer. All the data and test results are showed on a 320*240 LCD. All the test results could be printed by the micro printer or saved on the storage of the tester. The tester has a good performance on auto protection and anti-disturb. Main function and characterThe voltage ratio measurement of three or singe phase transformerThe group vector measurement of three phase transformer.The polarity measurement of single phase transformer or CT/PT (CT that knee-point voltage should be more than 80V)Voltage ratio error calculation Voltage ratio range calculation of three phase transformerCurrent transformer ratio measurementExcitation current measurement in ratio testingReproduction the AC test voltage from power source to reduce the effects of bad power source Save the test results in the memory internal the testerPrint the test results by micro printerReverse connection detect unit to prevent the high voltage injected to the operate Over current protection in test voltageUpload the test results to make word report by RS232 interfaceAutomatic transformer 1/10 turn ratio test meterMain technique index sign1.Ratio measurement range:1-100002.Group measurement:1-12 (12 vector groups)3.
