WHY TRANSFORMER RATING IS MENTIONED IN KVA RATHER THAN KW
Answer Posted / tank
The transformer is an apparatus which receives the power in
VA,KVA or MVA rating depending upon the capacity of the
transformer and it transforms/supplies the power under same
rating to a particular load when it is connected to a
transformer.In this process the power factor of the
connected load decides the KW rating(KVA X P.F = KW).Hence
transformer rating is never given in KW but always in VA,
KVA or MVA at manufacturing stage as there is uncertainity
of the type of the load and power factor to be connected
with the transformer.

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.
