voltagecurrentperformance

The Transformer CT PT Tester is a next-generation testing instrument for CT and PT, developed based on traditional transformer volt-ampere characteristic testers, ratio and polarity testers, and voltage regulators, voltage boosters, and current boosters. It was designed with extensive user feedback, thorough market research, and in-depth theoretical studies. The device features high-performance DSP and FPGA technology, advanced manufacturing processes, and ensures stable, reliable performance. It offers a complete range of functions, high automation, and high testing efficiency, making it one of the leading products in China. This instrument is a professional tool for testing transformers in the power industry. Main Technical Characteristics 1.Comprehensive Testing Functions: The instrument offers a wide range of testing capabilities, meeting the requirements for excitation characteristics (V-I curve), ratio, polarity, secondary winding resistance, secondary load, ratio error, and angle error of various CTs (including protection, measurement, and TP classes). It can also test the excitation characteristics, ratio, polarity, and secondary winding resistance of various PT electromagnetic units. 2.Automatic Parameter Calculation: The instrument automatically calculates and provides parameters such as the inflection point voltage/current, 10% (5%) error curve, accurate limit coefficient (ALF), instrument security factor (FS), secondary time constant (Ts), residual magnetic coefficient (Kr), and saturation inductance.
