Transformer ct pt comprehensive characteristics tester

★ It has comprehensive functions, which not only meets the test requirements of excitation characteristics (V-I characteristics), ratio, polarity, secondary winding resistance, secondary load, ratio error and angle error of various CT (such as: protection, measurement and TP class), but also can be used for the test of excitation characteristics, ratio, polarity, secondary winding resistance of various PT electromagnetic units.
★ The parameters of inflection point voltage / current, 10% (5%) error curve, accurate limit coefficient (ALF), instrument security coefficient (FS), secondary time constant (Ts), residual magnetic coefficient (Kr), and saturation inductance are automatically given.
★ The test meets the standards of transformers such as GB1208 (IEC60044-1), GB16847 (IEC60044-6), GB1207, etc., and is automatically selected according to the transformer type and level.
★ Based on the advanced low-frequency method test principle, it can deal with CT tests with inflection points of up to 80KV.
★ The instrument adopts the international popular square wave method to make the excitation curve more perfect.
★ The instrument can store 3000 sets of test data, power loss without loss.
★ The test is simple and convenient, to complete the CT direct resistance, excitation, ratio and polarity test with one key, and in addition to the load test, CT adopts the same wiring test.
★ Easy to carry, the instrument weighs about 7Kg.
