In order to optimize and analyse the performance of the controllable reactor of transformer type(CRT), the basic working principle of CRT is described, and its equivalent circuit model is set up. The operating characteristic,the harmonic characteristic,the control characteristic,and the volt-ampere characteristic of the reactor are analyzed, and the corresponding formula is given with waveform analysis, respectively. The active power consumption of CRT is calculated, and the active power consumption formula of the multi-winding transformer is derived. The response time of CRT is also calculated to obtain the transient waveform of CRT from one steady state to another.
