10. The circuit models is first constructed by using the electromagnetic transients program/alternative transients program. Then, the resonant voltages and currents and residual potential at customer main transformers are analyzed. Based on these analysis results, the affections on customer main transformers, and voltage transformers are evaluated. The study results had showed that over exciation currents will occurrence on main transformers and VT during low frequency resonant and very high residual voltages may arrised due to non-synchronous operation among poles of breaker. This very high residual voltage may lead to insulation failure on main transformer switchgears, VT and any equipments connected with the cables, even have tremendous impacts when cables are back -to- back re-energized.
文中首先以电磁暂态模型分析程式建构模型，然后分析前述各种状况下各用户端电压与主变压器电流之谐振情形及最终之残余电压，最后据此评估其影响，其中将分析地下环路供电系统因电力公司停电可能因低频谐振及残余电压造成用户主变压器与比压器损坏及电缆本身可能的伤害，研究结果显示低频谐振可能使主变压器及比压器的铁芯饱和，而造成长时间的过激磁电流使其受损，至於电力公司电源端三相不同时切离可造成过高的残余电压使GIS各设备及电缆接有过压之情形，尤其当电源再度投入时造成背对背加压，对电缆瞬间极大的冲击，必须加以防范。
11. Time graded schemes such as over-current or distance protection schemes are examples of those providing inherent back-up protection; the faulty section is normally isolated discriminatively by the time grading, but if the appropriate relay fails or the circuit breaker fails to trip, the next relay in the grading sequence will complete its operation and trip the associated circuit breaker, thereby interrupting the fault circuit one section further back.
过流保护或距离保护可作为前一种方案的例子，通常采用分时限区别来隔离故障段，如果相应的继电器拒动或断路器拒跳，按时限下一个继电器动作跳开有关的断路器，这样就断开了故障回路的下一段。采用这种方法就获得了完整的后备保护。
