Generally capacitors are connected across power supply for
power factor improvement and as a Harmonic filter. As we
know that capacitor having power storing property so when
power supply switch off all power stored by capacitors
discharge through connected load. That's why bulb goes off
slowly.

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.
