Lets take an example of 12 kV switchgear Panel. Generally they are internally housed. It consists of VCB,CT,PT inside itself. We dont have CTS or PTs or CBs outside in the switchyard for 11 kV.
Let us now consider 33 kV or 66 or 132 kV panels...they consist of Control & Relay panels for controlling equipments like CBs and DS. Its because CT,PT and breaker are located on the switchyard (external)while only the control panels are internally housed.
So the switchgear consists of CB+CT+PT +C&R Panel
while control gear just consists of Control & Relay panel only ..

( Re: WHAT SHOULD BE THE RATING OF MCCB FOR 415V,3Ph,50KVAR CAPACITOR BANK Answer # 1 The capacitor current would be kvar x 1000 / (415 x sqrt3). This would be 70a approx. The MCCB selected should have *atleast 1.4 times this current i.e. 1.4 x 70= 98. So you should choose at least 100 A mccb.) regarding to this answer,i would like to know why the current have to times 1.4 to get the right amphere for the mccb.hows the formula to get the 1.4??tq
