Why frame of the motor is specified?. If we mention KW and voltage level,automatically frame is decided or separately frame is compulsory to mention?.
DAE,
1 1811Is there any rule to select the voltage of motor based on KW rating? What is the rating above which lt motor becomes the HT motor?.
DAE,
1 1812Whether amorphous core transformer is available in India?.If available then up to what rating of voltage and KVA?.

what is mean by restructuring power system?
In PFI plant one stage capacitor connection is directly connected(with out megnetic contact controll). but why?
hi frenz,its aswathy.i hve aplied for the hpcl test on feb,pls send the test patern & the placement papers as soon as possible. mail-id :kjaswathy@gmail.com
Can Anyone Answer anyone of these ? Q1) why direct SOLUTION of Load Flow Studies in Not Possile ? Q2)Why majority of Buses in power system are load buses Q3)Why one of the buses in Power system is taken as reference bus (slack or swing) Bus ? Q4)Bus Admittance Matrix is a sparce (means it contains some zero elements ) matrix , give reason
when will be the iocl interview results i faced interview on 8th september 2008 iam from electrical branch i faced interview for the post of electrical engineer??????????????????????//

1- XC and the RC time constant are both measures of the reaction of C to a change in ____? 2-The power factor is a numerical ratio with a value between 0 and 1 equal to the ______________ of the phase angle. 3-When V and I are out of phase because of reactance, the product of V times I is called ______________ power 4-For _____________ inductors, the branch currents can be added algebraically. 5- The ______________ power in watts can be calculated as I^2R 6-Calculate XL with L = 30mH and f = 1kHz ( I have Xl=2piFL 2*3.141592653*1kHz*30mH =188 ohms Please check) 7-A parallel RL circuit has the values, R = 5kohms, XL = 5kohms. A voltage source of Vt = 10Vrms is connected in parallel to R and L. Determine the total current, It delivered by the voltage source Vt. 8-A series RC circuit has R = 1Mohm and C = 1microF. How long would it take for the capacitor to fully discharge if it is initially fully charged? 9-A circuit has real power = 300W and an apparent power of 500VA. Determine the power factor and phase angle. 10-The time constant for an LR series circuit is T = 0.1s and R = 10ohms. Calculate the inductance L.
