ZW20-12 Outdoor High Voltage Pole mounted Circuit Breaker

When there is a fault in the T-connected branch line of 10KV overhead distribution line or the end user, the outgoing switch of the substation will trip because the protection action time limit of the incoming switch cannot be reasonably adjusted in coordination with the protection time limit of the outgoing switch of the substation. If the fault is permanent and the substation reclosing will not be successful, a local accident within the medium voltage user boundary will cause the power failure of the entire 10KV distribution line.
