Lightning is a natural phenomenon that has very power large so it is easy to potentially disrupt the power grid system. upvoting comments from now on

This phenomenon can not be avoided because it can happen at any time and not
can be predicted when it comes. In addition to damage the power grid at the level
High voltage, lightning strike can also damage electrical equipment at the level
low voltage that is usually connected to homes. On the other hand
Indonesia is a country where all its territory is included in the region
tropical hot and humid, so it has that level of lightning strikes
higher than the countries in the subtropics, so
This lightning strike can cause damage to that network
has the worst impact that can turn off the economy of a State,
because all activities performed using electricity as a necessity
primary. In addition, the needs of the use of electronic devices have become
one of the main needs, not just a complement therefore
damage due to unpredictable things like a lightning strike
should be minimized as much as possible.
Lightning strikes that occur in high voltage networks can
causing more voltage and network damage, while on the channel
low voltage can damage the electronic devices that are usually in the house
