Electronic-voltage transformers for distributive mains

Requirements for electromagnetic, capacitance, and electronic voltage measuring transformers in 10- to 110-kV mains are clarified. The urgency of developing electronic-voltage transformers that will meet the requirements of upcoming international standards and have the function of standard analog output signals for actual substations is shown. Results of modeling are given that confirming that it is possible to use this innovation, which eliminates ferroresonance phenomena and PSP rearrangement and facilitates effects on equipment. Designs and specifications of 110-kV electronic transformers are given.
