dear all, in motor operation , motor is of 100 hp and
bimetal relay setting is 130 amp, if relay is getting
tripped on 120 amp balance current what can be the
reason? Relay is newly replaced. I dont know but is
there any frequency effect in thit case? Can frequency
variation affect bimetal relay operation?
Bimetallic relays are not very accurate.Ambient temp also
plays a role for setting as the relay acts at a certain
temp.Hence you have to compensate for ambient
temp.Frequency has no effect on the setting .

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?
