Although the first thesis on Ferroresonance was published in 1920, FR is still not a fully understood phenomenon. This thesis focuses on single phase FR in Gas Insulated Switchgearwith inductive potential transformers, fed by the circuit breaker grading capacitance. In principle, FR is a forced oscillation in a non-linear series resonance circuit including a capacitance and non-linear inductance, which shows significantly distorted voltage and current waveforms.

中文摘要虽然第一篇有关铁磁共振（Ferroresonance，简称FR）的文献早在1920年即被发表，但是此一特殊的现象至今仍然未被完全了解，本论文将讨论电力系统中之气封绝缘开关设备（Gas Insulated Switchgear，简称GIS），由於断路器的极间电容和电感型比压器（Potential Transformer，简称PT）的非线性电感所构成的单相铁磁共振；理论上，铁磁共振是由电容和非线性电感所构成的非线性串联共振，造成电压和电流波形明显的畸变。
