Static
Electricity is just that; electrical energy that is standing still
or static, and, therefore, ready to move at any time. These cashes
of electricity, or charges will move towards the earth or ground
as soon as there is a conductive path that they can follow.
Anything that conducts electricity will work.
That includes metal, water and even people. If there is enough
power in the charge and enough attraction between the source of
the charge and the ground target, the electricity can actually
jump or fly to that ground point.
Some examples of that phenomenon are lightening
bolts flowing from clouds to the earth below and, more to our
point, that painful shock you get after walking across a carpet
and reaching out for the door knob on the other side of the room.
ZAP!!!
The force of that static electric discharge can
leave welts on you and can destroy sensitive electrical equipment,
such as computer parts, if they are on the receiving end of the
discharge or even if they are standing in the path of the flow
of the charge. Like a fuse that breaks when too much electricity
is flowing through it in order to protect the wiring beyond from
melting, the sensitive electronic components in the way of a static
electric discharge may break from the force of the charge. If
that happens, often times it is difficult to find the failure
and hours of downtime can result, also loss of memory or other
similar problems may result.
That is where anti-static mats and other anti-static
products come in to play. The more sensitive the machines or products
are the more care must or should be taken to protect against potential
damage that discharges of static electricity could cause. The
protection comes in the way of diverting the electrical charges
to ground or at least away from the products or machines to be
protected.
Static adaptive
mats are engineered to attract and gather potential static electric
discharges and either dissipate that electrical energy into the
mat and in time into the atmosphere, or, when outfitted with properly
installed and sufficient numbers of ground wires, will continually
drain the electrical charges they gather to ground. Ungrounded
static dissipative mats will serves well for every day uses found
in most office settings.
When computers
are open for service, or when there are sensitive electronic parts
being transported, or stored, or being used in the manufacture
of sophisticated equipment, their exposure to harm from static
electricity is greater since thay may not benefit from the normal
protective devises included in many finished pieces of equipment.
Simple static
dissipative mats leave too much to chance with regard to protecting
such parts and machines from harm. In those situations, the grounding
wires described earlier with one-ohm resistors, to protect against
a reverse flow of electricity, which could harm and potentially
electrocute the user of the mat, are needed.
Each grounding
cord has an effective range of about four-feet in diameter. Larger
mats would require a deployment of grounding cords that will overlap
each of the other fields of coverage, to insure that potential
electrical build up is constantly being taken to ground.
It would seem
that with the right mats in place there would be no more problems
with static electric damage. But, users who insulate electrically
themselves from coming in contact with the mat by wearing non-condictive
shoes such as sneakers, or crape sole shoes can defeat these mats.
To make sure that this does not happen, special footgear that
fits over the shoes and attaches directly to the user’s
calf are employed.
