Answer Posted / will
Lightning occurs when the negative charged cloud and
positive charged clouds hit together.A flash occurs and it
tries to conduct through the atmosphere.
Protection through lightning is achieved by installting the
lightning arrestors at the top of the high rise buildings
and grounded separately.The grounding shall be separated
from the normal ground grid in the petrochemical plants.
We need not to select the height for the spike , when the
building or the equipment is proted by lightning arrestor ,
the lightning arrestor will take care, The surge will be
arrested by the lightning arrestor and current will
directly flow to the ground without causing any damage to
the equipment(Substation) or the high rise buildings.

A commercial Building is designed with 14th floor levels with indoor substation of three phase transformer with rated capacity of 1000 Kva.The transformer delivered 65% of its rated capacity at 0.67 power factor lagging.Because of low power factor, the power customer was penalized and certain cost was charged accordingly based on every point percentage lower than 85%.This situation may repeatedly happen on the succeding energy bills of power customer.The power customer is desired to improve its historical power factor of 0.67 lagging and no further penalty be impose by the local power company on the next bill.
