Answer Posted / nishant

For staring of Motor above 5 HP we need a starter with
overload protection e.g. Star-Delta Starter and D.O.L.
Starter for limiting starting current as motor takes 5-7
times of its full load current during starting So if we
start 20 HP motor Directly the line fuses will Blown Off
due to high starting current.

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?
