When normal operation the saturated transformer type SSFCL is equivalent to original transformer coupling solid state fault current limiter, but the coupling transformer coil enters deep saturation when short circuit fault occurs. After the SCR bridge withdraws from the system connection, the saturated coil reactance and the leakage reactance of coupling transformer play the role of limiting stable short-circuit current, equivalent to SSFCL with bypass inductance.
饱和变压器型固态限流器正常运行时等效于原来的变压器耦合固态限流器；但在短路限流时允许耦合变压器铁心进入深饱和；在桥路退出系统后，饱和激磁电抗和漏抗起到限制稳态短路电流的作用，等效于带旁路电感的固态限流器。
In medium voltage network, when phase to ground voltage appears asymmetry and some phase voltage rises, the iron core of PT becomes saturated, its excitation inductance decreases, when to match the capacitance of the system, ferroresonance occurs.
在中压配电网中，当系统对地电压出现不对称且某些相电压升高时，PT铁芯出现饱和，其励磁电感减小，当与系统对地电容达到匹配时发生谐振。
Characteristics such as the switching time, interlamination voltage, saturated inductance, and loss of the core, which can affect the performance of the magnetic switch, are derived in the case of the fast pulse input.
