how on load transformer is chnage the Tapping ?

Answer Posted / sewagudde

the automatic voltage regulator (AVR) senses changes in
voltage and sends a signal to the controller on the tap
changer to either raise or lower the tap.it should be noted
that the tap changer is always located on the HV side of
the transformer inorder to interrupt smaller currents as
compared to the LV side

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?
