You might wonder if the surge protector installed at the service entrance would also protect equipment within the facility 你可能想知道安装在总进线端的电涌保护器是否也会保护建筑内的设备。
Check installation and connections between transformer and all switchboards and among each other and of the main incomers 确认变压器与各段母线，各段母线之间以及母线进线柜之间已正确安装连接。
The heavy - duty service entrance protector is too far away , inductance - wise , to be able to limit locally developed transients 因为这个重型的进线端的保护器，由于距离太远、电感的原因，不能有效地抑制局部产生的电涌。
This system is consisted of these different sub - systems : the main circuit , the control system , input transfer , and three circumfluence reactors 该装置主要包括：主回路，控制回路，进线电源变压器以及环流电抗器等。
