Answer Posted / michael
Amp consume by the capacitor simply Q = VIrf
where rf = sin theta, since it is
capacitor so theta = 90 deg
sin 90 = 1
so simple I = Q/V
Q = reactive power
V = voltage
I = current
(KVA)^2 = KW^2 + KVAR^2
since purely capacitiy KW = 0
therefore KVA = KVAR..
NOTE : in a purely capacitive or inductive
real power always Zero

Which type of transformer is used for lighting loads?
I'm generating a pulse of 3V with frequency 80Hz (12.5ms time period) and pulse duration 0.125ms and feeding it to a transformer since i want the pulse to get amplified around 60V. At the output amplification s happening but the pulse is changed to a spike, can you tell me what could be the reason? (an ordinary transformer 220V-12V stepdown transformer is reverse connected ie. now it is 12V-220V stepup and voltage amplification happens)

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?
