The voltage ratio of the capacitor and reactor will change when the fault occurs.
电抗器匝间故障时，电容器与电抗器电压比将发生变化；
2
Routine shunt reactor fixed on the EHV transmission system can not guarantee the transmission capability and steady state voltage of system under different operation modes.
常规并联电抗器固定接入超高压输电系统，不能保证各种运行方式下系统输送能力和母线的稳态电压。

ATP simulation and MATLAB calculation show that the voltage ratio protection against inter-turn fault of reactor can make correct judgement to this kind of fault quickly.
