2 4477why ups rating in kva? and why ups are in parellel?.why isolation transformer is used in ups?
1 2013I know during Surge Impedance Loading maximum power is transferred through a transmission line and also Sending end voltage becomes equal to Receiving end voltage i.e Vs=Vr so my question is if both end voltages are equal then how current travels in such line hence how power is transmitted because flow of current needs Potential difference??
NTPC,
3 6177For a 6.6kV Motor it is recommended to do megger test with 500 V d.c and not more than 5kV d.c but the Hi voltage withstand test should be performed by 12kV AC. Why the dc voltage test should be limited but AC voltage withstand test could be with such a high voltage?

What is the basic principal, by which DC voltage level is increased more than the supplied AC voltage during conversion. As upto AC level it is contorrled by firing anlge but after maximum level how is it possible.Please clear picture. OR we have to supply the higher level AC?
pls,send the previous year written test questions.
Q.1:What protection will be used on HT and LT side of 33/0.4 KV, MVA transformer. Indicate capacities of protective device to be used.
