Answer / pradyumna chandra panda
Ans- There is a mechanical speed (s) in every motor,
designed by Manufacture Company according to
construction of motor that should be not less than
synchronous speed.
If we give 60 Hz supply to a motor (which rating is 50 Hz)
there will increase (20%) the synchronous speed then rotor
of that motor tends to rotate at higher rate , no any
trouble will occur be, but there should be support the
mechanical speed (s) and load.

As we all are aware with formule
NS=120f/P, if we change f(frequency) the syn.speed will
change as these quantities are directly proportional to each
other.

Answer / shahbaz
As we knw that sync speed is 120f/p hens as f increases speed increases but our eddy current losses and hystresis losses are functin of frq hence losses also increases

Answer / kj
First the motor will run faster as the speed is determined
by the frequency. A 4 pole motor will induction motor will
run at about 1440 rpm at 50 Hz. At 60Hz it will run at
about 1730 rpm.
Where the problem may be is that a 50Hz motor will have
more iron in the core and will need a higher voltage to
produce the correct strength magnet field.

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
