It seems two types of issue:
1. Out of house 电力系统部分受雷电冲击而开关跳闸,但开关有自动重合功能,所以马上会恢复送电.
2. In house 自家的电路受雷电冲击.
I am not sure which one was impact on my house. If the reason is (1), should I contact builder first to report this issue? If the reason is (2), should builder has the sugar protector for whole house installed before closing? Or I have to install one by myself?
Many thanks
