Answer Posted / gunasekaran
one voltage level single earthing is recommended that is at
source for G.T generator is source it is already earthed.if
we use star we have to do the earthing so delta connection
is preferred.for distribution sending end is already earthed
at substation so HV side of the distribution transformer is
delta for LV side transformer is source so star with earthed
neutral. if two earthing is provided zoro sequence current
getting closed path so wave farm become distracted.

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?
