How to design and select surge protectors?
Thread Content
On the incoming cable cabinet side of the low-voltage distribution room, how should the surge protectors for outdoor to indoor lighting or those on the side of the Donglei distribution box be selected? Thank you
Generally, on the incoming side, we choose a residual voltage of 2500V and a current of 100KA; this is the first stage. Output selection: 1500-2000V, current 40KA, second stage. Third level, 1200V, 10KA
