Answer Posted / bapan
If Dc supply is given to atransformer there will be no change in the flux with time.so,there is no emf induced in the primary and secondary winding and hence transformer action will not take place.

54 Comments Alok and Bhanu play the following min-max game. Given the expression N = 38 + X*(Y – Z) where X, Y and Z are variables representing single digits (0 to 9), Alok would like to maximize N while Bhanu would like to minimize it. Towards this end, Alok chooses a single digit number and Bhanu substitutes this for a variable of her choice (X, Y or Z). Alok then chooses the next value and Bhanu, the variable to substitute the value. Finally Alok proposes the value for the remaining variable. Assuming both play to their optimal strategies, the value of N at the end of the game would be?
Why it is possible to use PWM with a STATCOM and not with a conventional TCR based SVC
sir, what is the importance of Fault MVA. how to calculate fault mva of 33kv substation connected by 6.5 km line(single circuit with equal spacing) with 110/11kv transformer in 110kv susbstation.the fault mva on 11 kv bus in 110kv susbstation is 208mva.

need to make a report. Need to choose a 3phase induction motor. Load conditions motor will operate in : Maximum Load: 30 Kw Speed: 2950 rpm Ambient temp: 20 cent Supply voltage: 440V Frequency: 50Hz need to look for the safety factor when choosing the motor, went through catalouge found a few, but dont know how to choose the safety factor allowing an extra load something above 30 KW to avoid any harm.

For refrigerators the motor current is raised beyond its rating on both conditions when the voltage of the system is more(say 270v) than the rated voltage(220v) as well as when the voltage of system is less(say 160v) than normal voltageof 220v, why explain?
