Answer / gajanan

non linear loads means semi conductor devices. each semi
cond device has junction capacitance.when such devices are
swithed on or off the junction capa takes inrush current
which produces hormonics

What can be a rating of a transformer(KVA) if the load is about 1000KW?illustrate by showing formula?

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?
