You need to figure in resistance also. The formula is
I=E/R. Current (I) = Voltage (E) divided by Resistance (R).
At the same resistance, if voltage goes up, so does current.

In DC current-excitation to transformer, why it sucks more current? Eventhough there is no power transfer between primary and secondary? R is very low so it should suck less current only na thn y its current increases?

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.
