Lightning
Rods Are Proven Effective
Lightning strikes
American soil 30 million to 50 million times each year.
During our studies, we have examined the protection offered
by lightning rods although GE does not make or sell
lightning rods. We have studied their operation in detail
and are convinced of their effectiveness when properly
installed.
How
Lightning Rods Work
A lightning rod will
not prevent your house from being struck by lightning,
however they do prevent damage in the event that a stroke
does occur.
The principle is simple: quality lightning rods are made of material
that conducts electricity easily. A lightning rod works by
receiving the stroke and discharging it quickly and
harmlessly to conducting earth. Lightning rods are so
effective in conducting the stroke to the ground, occupants
in the protected building are often unaware that the
building has been struck.

A lightning bolt
generates heat up to 15,000 °C. This heat often ignites a
large area instantly. The voltage in an ordinary electrical
system using two wires is 110 volts. If your building uses
electric machines it generally has an electrical entrance
with three wires and your electric motors are generally
using 220 volts. If you are using such things as electric
ovens, you may be using up to 440 volts. In comparison, the
power of a bolt of lightning has been measured above
50,000,000 volts. That is 200,000
times more power than the voltage in your electrical system.
If you have ever been around a building where 40 or 50 cows
have been killed standing in a metal-clad building, you will
have a realization of the immense power that a lightning
bolt delivers.
A single lightning bolt has been measured above 3,750
million kilowatts. When such power is generated in .003
fractions of a second, you can understand why a metal
building has been found by the insurance companies that
insure thousands of metal-clad grain elevators on a mass
scale, that such metal-clad structures do not cope with a
lightning bolt until they are equipped with an underwriters
approved certified lightning protection system.
When the air terminals are left off a lightning protection
system, the action is to attempt to conduct this huge power
that is present in a lightning bolt. When the air terminals
are in use, the action is to dissipate the static load and
to keep it from accumulating a sufficient body to create a
lightning discharge.
