if i conncet ct with ct ratio of 600/5 to an energy meter
having ct ratio of 100/5, the reading show by the meter
will correct, if wrong is there any method to calculate
correct value with shown value, if yes please state
it.....
Answer Posted / wareagle
If the meter is designed to use a 100/5 ct, it will receive
5 amps when the load is 100 amps. If the ct were a 600/5,
the meter would receive only 1/6 x 5 amps or 0.83 amps
which would be a low reading. You would need to multiply
the reading by 6 to get the correct value. You would likely
not get the the exact reading with the 600/5.

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?
