Voltage transformer is used for protection of high voltage
distribution transformer. It Compare the primary and
secondary voltage ratio of a transformer and to maintain
fixed voltage at secondary terminal, it sense to auto tap
changer of the transformer to maintain fixed voltage during
no load to full load.
Potential transformer is used for measuring heigh voltage.
It's Primery windings is connected to the high voltage
source & secondary voltage is only 110 volts

How many types of colling system it trformers?
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?

we have earthmat at 110KV substation.we would like to take earth resistance.b some says that by connecting earth megger terminals (C1,P1) at middile point of earthmat (at riser) will cause voltage gradient at other earthmat nods and dont get exat earth resistance.when connecting at end nods will get exat value . is it correct .please explain
