If you refer to the STAR connection of transformer winding, Its neutral point is connected to ground, Hence neutral is always at ground potential ( provided solid neutral earthing). Hence tester will not glow as it is at ground potential. Now the matter is current is flowing through the neutral is because of unbalance or fault in the system which will go to ground.

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?
