anyone please send transformer parameter design formulas & details of tap changer ? plz i have interview this week its more helpful for me ?
what is R Core Transformer. how it differs from normal transformers. dont search in net and post the answer.
what is submersible pump?what is different between motor and sub motor?
following are the questions asked in interviews: 1) Considering the short circuit fault, which switchgear is preferable, SFU OR MCCB? Which operates faster? whicg one is popular in Indian Market and why? 2)Define SCPD. What is type2 coodination? 3)Why the contactor rating is higher for the fuseless selection than for fuse selection? whether the ratinf of SFU or MCCB remains the same in both the cases? 4)If the HP rating is known then can you calculate the ratings of L.V Switchgear(SFU/MCCB, contactor, OLR) without using the selection chart?
