Class 0.1 Variable-frequency Method Instrument Transformer Excitation Burden DC Resistance Ratio Pha

Features:1. Full-functioned, not only satisfy testing requirements of various CTs (include TP class), such as the excitation characteristics (volt-ampere characteristics), ratio, polarity, secondary winding resistance, secondary burden, ratio error and phase displacement, but also can be used for tests of various PTs, including excitation characteristics of the electromagnetic unit, ratio, polarity, secondary winding resistance, ratio error.2. No need standard transformers, booster, load box, voltage control box or primary current leads, simple wiring and simple operation3. Test CT/PT A/V characteristics curve and 10% error curve based on advanced viarable frequency method,CT knee voltage up to to 60KV.4.can measure ratio error and angle error with high precision5. Automatically display parameters like knee point voltage / current,10%(5%) error curve, accuracy limit factor (ALF), instrument security factor (FS), the second time constant (Ts), remanent coefficient (Kr), saturated and unsaturated inductance etc.6.Meet standards of IEC60044-1, IEC60044-6, auto choose testing standard in accordance with the transformer types and levels 7.One click can finish CT DC resistance, excitation, ratio, polarity test. One wire connection mode for all CT test except load test8.Friendly interface
