Research on Energy Optimization of Double Air Gap Model Current Transformer

To investigate the energy acquisition issue of current transformers (CTs) for online power supply to highvoltage transmission lines, this paper employs finite element simulation to study the differences in energy acquisition between single and double air gap model CTs. The effects of varying air gap width, primary current magnitude, and load size on the energy acquisition of CTs under the double air gap model are examined. Ultimately, the optimal load points for maximum energy acquisition under different conditions are identified, and the qualitative impact of external conditions on the excitation reactance is analyzed.
