EDG shall be connected to6 kV bus directly and subsequent reduction shall be possible. Normally there would be two different categories of power consumers - Emergency category (E- grade) and Normal category (N - grade). EDG shall supply to only E- grade power consumers which are very much essential to keep running all the time. DEG 是用来处理一些紧急情况的, 如外界电源中断, 电讯中断,等. 一般来说, 电力是从外部以 110kv 需要直接与 6kv 母线相连, 若可能的话还要与后面的变压器相连. 一般来说, 有两种种类不同的电力用户-- 紧急种类(E- grade) 和正常种类(N - g
