WJP-1000 Transformer Comprehensive Tester
Main technical features
★Comprehensive functions, it not only meets the test requirements of excitation characteristics (i.e. volt-ampere characteristics), transformation ratio, polarity, secondary winding resistance, secondary load, ratio difference and angle difference of various CTs (such as protection type, measurement type, TP type), but can also be used to test the excitation characteristics, transformation ratio, polarity, secondary winding resistance, etc. of various PT electromagnetic units.
★Automatically provide inflection point voltage/current, 10% (5%) error curve, accuracy limit factor (ALF), instrument safety factor (FS), quadratic time constant (Ts), residual magnetization coefficient (Kr), saturated inductance and other CT and PT parameters.
★The test meets various transformer standards such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, etc., and automatically selects which standard to test according to the type and level of the transformer.
★Based on the advanced low-frequency test principle, it can handle CT tests with inflection points up to 30KV.
★The device adopts the internationally popular square wave method to make the excitation curve more perfect.
★The device has a storage capacity of up to several G and can store hundreds of thousands of sets of test data without loss of power outage. After the test is completed, an Excel report is generated directly.
★The test is simple and convenient. CT direct resistance, excitation, transformation ratio and polarity tests can be completed with one click. In addition to the load test, all other CT tests use the same wiring method.
★Easy to carry, the total weight of the device including wiring is about 8Kg.
