英文不好，有点迷糊，求助！！！Current sense transformer ratio 1:500 Have to able to sense currents under normal conditions that means max. 500A. Under this max. requirements the current sense transformer must give correct signals. The burden that is used at the end of the current sense transformer is 18 Ohm. The current sense transformer case dimensions are nearly l*b*h of 49,5mm*49,5mm*27,5mm. The sense hole is nearly 19mm. The output of the transformer is with two fast terminal with 6,3mm*0,8mm and nearly 32mm centre to centre between each terminal. This CT have 500 windings with 0,40mm wire to a nearly OD*ID*HT (40mm*30mm*16mm) silicon steel core.

低压命名体系相对于高压十分混乱。

对于抽屉柜，有几种命名方式：C-抽屉，H-混装
于是GCK等是一系；GHD也成了一系。
乱！
柜：D、P等，呵呵
