what is the generator rating for 40 amp load of 3phase motor.?? 400v voltage of generator... plz tell me with formula its urgent...plzzz... and also tell me that this 40 amp at all phases mean 40 amp on red,40 amp on yellow,40 amp on blue...... or the total sum of that 3phase is 40 amp....
A logic circuit that provides a HIGH output if one input or the other input, but not both, is HIGH, is a(n)?
We have a couple of oil tanks at our plant. One of them does not have a lightning arrester installed. My question is it necessary to install an arrestor on every tank or will this particular one be covered by the arrestor installed on the ajdacent tank, Since all the tanks are close to each other. Basically, I want to know that if these arrestors or protection works in a parituclar area of effect or influence. Thanks
