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.

I need to compare the energy consumption of an industrial machine before and after improving. Shall I compare the apparent power or the active power? I know usually factories use compensated capacitors (or other similar components) to compensate the reactive power, so if I use the apparent power, it's not the real power consumed.
