1. Comprehensive functions, it does not only comply with testing requirements for excitation characteristics, transformation ratio, polarity, secondary winding resistance, secondary load, ratio error, angle difference, etc. of various CTs (such as protection category, metering category and TP category), but also can be used to test excitation characteristics, transformation ratio, polarity, secondary winding resistance, ratio error, angular difference, etc. of various PT electromagnetic units.
2. Automatically offer voltage/current of an inflection point, 10% (5%) error curve, accuracy limit factor (ALF), factors of instrument safety (FS), secondary time constant (Ts), remanence coefficiency (Kr), saturated and unsaturated inductance and other CT and PT parameters.
3. Test complies with various instrument transformer standards of GB1208 (IEC60044-1), GB16847(IEC60044-6), GB1207, etc., and able to automatically select standards to test according to instrument transformer type and grade.
4. Based on advanced low-frequency testing principle, and able to do the CT test at the inflection point of 30KV.
5. Friendly and beautiful interface, all-in-Chinese graphic interface
6. The device can save 1000 sets of testing data, which cannot be lost in case of power failure. And it is able to preserve in PC computer with U-disk after test, analyze data with software, can generate WORD report.
7. Simple and convenient test, able to finish CT DC resistance, excitation, transformation ratio and polarity test by pressing one key, and except for load test, other CT tests all adopt the same wiring method.
