For an 100kw generator, only 50kw of load is connected. will the generator generate only 50kw or 100kw. if it generate 100kw what happens to rest of the 50kw. what happens if we connect more than 100kw of load?8 15594
In a synchronous motor armature current flows due to revolving flux which in turn rotates the load,but in no load condition armature current is zero hence thr is no revolving flux then how motor rotates?9 10622

What is the direction of current flow in ct secondary...means if the current is flowing from P1 to P2 then what will be the direction of current flow in ct secondaryw
how to select diiferent power transformers of same capacity on no load loss and full load loss by economical point of view.?
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?
