why a pilot exciter is used in combination with the main exciter?
why not only a main exciter is used for excitation to an alternator?
Answer Posted / ud
Pilot exciter is used in combination with main exciter to increase the quickness of response of the excitation system.
In case of increase in reactive power demand(voltage stability) or sudden load changes( transient stability) , the excitation system must respond very quickly.
By using pilot exciter, quickness of response is increased.

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
