Charge Dissipation,
a powerful tool.
Charge dissipation to prevent lightning and eliminate static electricity has developed
into a useful tool in preventing damage to sensitive electronic equipment. With the
increased usage of computers and microprocessing in communications, instrumentation and
automatic controls, facilities have become more vulnerable to failures and outages due
to the effects of lightning, power surges and transient voltages.
How Does It Work?
Before and during a thunderstorm, electric fields of extremely high voltages build
up. If the energy in these fields is not dissipated, arcing and breakdown of
insulation can occur, leading to damage in solid state components. Dissipation
works by slowly discharging the energy in the fields over a relatively long time
period at very low current levels, rather than by the instantaneous high current
discharge from a lightning strike.
When Does It Work?
As a storm approaches and the voltage of the electric field builds up, each sharp point
within the dissipation array begins to conduct into the surrounding air by ionizing the
air molecules above it. If enough points are available and are arranged in the proper
geometric configuration, the energy in the electric field is slowly dissipated by
conduction of the points into the air. The field voltages needed for lightning will
never be attained.
Is This Something New?
This is a scientific process first touched on by Benjamin Franklin more than two
centuries ago. However, since then, and most notably over the last twenty years, the
technology of static charge dissipation has developed to the point where damage to
electronic equipment can be reduced from 90 to 99 percent, depending on the site and
storm intensity. Many sites have never had a recurrence of lightning after installing
a properly engineered dissipation array.

Gila-Stat
The Gila-Stat is an improved version of a design that has had great success for
more than 15 years. Constructed of stainless steel and high quality aluminum, it is
extremely rugged to survive the worst weather conditions for many years. Unlike some
dissipators that are made with thin wires that can be damaged by wind, ice and hail,
the Gila-Stat is made with 1/8" stainless steel individually sharpened rods which will
not be damaged by weather, birds or other hazards.
Included is a mount which is custom manufactured to suit the customer's application.
Normally a ground wire is not needed if there is an adequate path for the small
electrical current, but ground wire and ground rods can be supplied. There must be a
path of low resistance to the current to ground, but his is not difficult to attain.
The Gila-Stat can be used singly or as a system of dissipators for large facilities
such as cogeneration plants or tall broadcast or communications towers.
