Brushed alternator is also called dc generator ? its true
or false ?explain it ?

Answer Posted / thuranga

I exactly does not know the right answer for it...but what I
think is ,in the alternator the AC voltage collected at
sliprings where it turns out to be ac becoz there will be
not breaks as on commutator(for DC gen/mot)

so as far as I know if the alternator consists the mica gaps
on the shaft or commutator then it acts DC gen....
but without those gaps even if we put the brushes also the
current collected at brushes will be ac only.but the only
problem is the maximum power will be wasted at the brushes.
(this is my view,tell me if it is wrong).thanking you

L.A. (Lightening Arrester) is located at a place from where transmission line enters the transmitting substation. So L.A. (Lightening Arrester) is the first equipments which has to encounter with lightening, high voltage surges and switching surges. It has to absorb energy of lightening, high voltage surges, and switching surges. L.A. (Lightening Arrester) is made up of layers of semiconductors. If these layers can not tolerate energy released by lightening, high voltage surges, and switching surges the L.A. (Lightening Arrester) blasts.
