Now That I Have This Information, What Do I
Do with It?
There are two ways to solve most power line
disturbances: either rewire the electrical system to
separate the sensitive loads from the problem
branches, or place a number of UPS’s or other
protection devices in mission critical areas. The problem
with using a UPS is it may introduce more disturbances
downstream of the electrical system as it may use a
switch mode power supply. A UPS is only a temporary
solution. The real problem is probably located
somewhere in your electrical distribution system. Poor
wiring, poor connections, poor load distribution or
improper grounding may be the problem.
When trying to solve power line disturbances, consider
the following:
• The power requirements of the sensitive electronic
equipment
• The severity of the problem
• The effectiveness of each possible type of power
conditioner
• the performance/price relationship
Repetitive / Cycling Events
These types of events are usually caused by
incompatible loads on a circuit. HVAC systems, laser
printers, and large motors may cause conflicts when
they cycle. These types of conflicts occur because the
building’s electrical demand has increased, and there is
no one responsible for monitoring the load on the
system until there is a problem. Moving sensitive loads
to a separate circuit may solve this problem.
Unrepetitive / Isolated Events
These types of disturbances are usually caused by the
location of the organization. If you are in an area where
there is lightning, high winds, or if the equipment is
being used only occasionally, simple power line
conditioners and filters may help to protect most of the
equipment. Many power line disturbances are easy and
inexpensive to prevent (depending on their frequency
and magnitude).
