"Instrument Transformer Comprehensive Parameter Tester", also known as Inverter Transformer Tester, Transformer Comprehensive Tester, PT, CT Characteristics Inverter Transformer Tester is a fully automated PT, CT characteristics inverter transformer comprehensive power test using frequency conversion technology Instrument, variable frequency transformer tester for CT volt-ampere characteristic test, PT volt-ampere characteristic test, CT polarity test, PT polarity test, CT variable ratio polarity test and PT variable ratio polarity test, comprehensive test instrument for variable frequency transformer Automatic calculation of the error curve of any point of CT, CT/PT variable ratio, ratio difference and other result parameters. I will use Hengxin Guoyi's "GY-HG Transformer Comprehensive Parameter Tester" as an example. Pay attention to the following points when purchasing the "Transformer Comprehensive Parameter Tester": 1. The transformer comprehensive parameter tester supports the detection of CT and PT (protection, measurement, TP) steady-state and instantaneous parameters. 2. There is no need to connect other auxiliary equipment, all testing items can be completed in a single machine. 3. The test is simple and convenient. CT direct resistance, excitation, ratio and polarity tests can be completed with one click. Besides the load test, all other CT tests use the same wiring method. 4. Comes with a micro-fast printer, which can directly print test results on site. 5. Large-screen LCD, graphical display interface. 6. The frequency conversion transformer comprehensive tester automatically gives (excitation) inflection point value according to regulations. 7. Automatically give 5% and 10% error curves. 8. The instrument's comprehensive parameter tester supports U disk dumping data, which can be read through a standard PC and generates a WORD report.
