3 18249what is mean by hvdc transmission technology .what is principle of hvdc transmission and technic of hvddc transmission .
1 4758What is the major differences between RCCB & ELCB? If we use ELCB of less sensitivity why does it trip often and can we control it from tripping?
1 6777( 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
