Abstract
With the development of electric power system, Power-frequency Magnetic Field (MF) has become a matter of concern recently. In order to speed up the computation and modeling process, the small-scale experimental technique and simplified model for air-core reactors are introduced as a novel way to assess the MF of air-core reactors in this paper. Firstly, the scaling rules of the parameters for air-core reactors are summarized. Then, the scaling rules modification is put forward to reduce the error. Thirdly, three simplified models were established for air-core reactors, including one loop model, two loops model and three loops model. It is concluded after that the two loops model in configuration 2 can be considered as the optimal simplified model.
