(1) Maximum continuous operating voltage Uc: The maximum continuous operating voltage Uc of the surge protective device low-voltage lightning surge protection device should be greater than the continuous operating voltage Ucs of the power system;
(2) The UT value of the surge protector low-voltage lightning surge protector should be higher than the temporary overvoltage (TOV) expected to occur on the back protection device due to a fault in the low-voltage system
(3) In is related to the protection level Up, while Iimp and Imax are determined by the ability of the installation point to withstand
