In UPFC,What is the need for Dc link ( DC capatior)?
what is transformer
how can we rotate a single phase motor (without cap.)in reverse direction?
Why Utility Distribution System in India is mainly at 11 kV? Why not Utility go for 33 kV?
i asked a funny question in Electrical ohms law V=IR in const temp voltage is directly proportional to current Power p=VI cos@ in that formula Voltage is indirectly proportional to current Try to give me the fact what is happening in Electrical.. contact Thanigai_1984@yahoo.co.in
What are two contours of nichols chart?
tell how current tranfomer works
How to Calculate Current Rating of SDFU (Switch Disconnector Fuse unit) for Protectionof Capacitor Bank connected to Busbar of 800Amp,in LV side of 11/0.433KV, 250KVA Transformer?
minimu size and length of gi earth pipe
Which oil can be used in transformer?
how can i increase the excitation on full load running engine??
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?
why in transformer there is not rotating fiddl/ magnetic field like motor
