Accordingly, effective methods of SMT selection are presented with the help of literature review. Whats more, two or more SPD will be installed in low-voltage electrical system. Energy coordination between SPDs is introduced as well. Keyword：Surge protection device, ZnO varistors, Parallel connection, Energy coordination, Combination performance
