why induction motors are of lagging type and not leading
type
Answer Posted / iamdon
Induction motor is a singly excited machine.It means there
is no scope of power variation by varying the excitation.So
the nature of power factor is solely decided by the nature
of winding,which is moslty inductive.Thats why Induction
motor has always lagging power factor.

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
