The Problem With Power
We
live in the Information Age where countless data is created,
transmitted, and stored. We live in the Electronics Age where numerous
electric-powered machines aid in business and household tasks, as well
as entertain and inform us. The reality of living in this time of
technological innovation is that the power to run these machines can't
keep up (at least not yet). What was built years ago for powering
factories producing manufactured goods is struggling to adapt to
provide continuous, sufficient-grade power to sensitive electronics
processing valuable information. Adequate surge suppression and backup
sources of power are a necessity to keep your business up and running.
Spring weather increases the likelihood of electrical disturbances
that can cause downtime and lack of productivity. And It's not just a
total blackout that can cause a problem.
Read on to find out about the
many power events that affect your critical data. And then, if you
feel you are not prepared, contact us to find out what it would take
to protect your business:
Sags:
Also known as brownouts, sags are short term decreases in voltage
levels. This is the most common power problem, accounting for 87% of
all power disturbances according to a study by Bell Labs.
CAUSE - Sags are
usually caused by the start-up power demands of many electrical
devices (including motors, compressors, elevators, shop tools, etc.)
Electric companies use sags to cope with extraordinary power
demands. In a procedure known as rolling brownouts, the utility will
systematically lower voltage levels in certain areas for hours or
days at a time. Hot Summer days, when air conditioning requirements
are at their peak, will often prompt rolling brownouts.
EFFECT - A sag can starve a computer of the power it needs to
function, and cause frozen keyboards and unexpected system crashes
which both result in lost or corrupted data. Sags also reduce the
efficiency and life span of electrical equipment, particularly
motors.
Blackout:
Total loss of utility power.
CAUSE - Blackouts
are caused by excessive demand on the power grid, lightning storms,
ice on power lines, car accidents, backhoes, earthquakes and other
catastrophies.
EFFECT - Current work in RAM or cache is lost. The hard drive
File Allocation Table (FAT) may also be lost, which results in total
loss of data stored on drive.
Spike:
Also referred to as an impulse, a spike is an instantaneous, dramatic
increase in voltage. Akin to the force of a tidal wave, a spike can
enter electronic equipment through AC, network, serial or phone lines
and damage or completely destroy components.
CAUSE - Spikes are
typically caused by a nearby lightning strike. Spikes can also occur
when utility power comes back on line after having been knocked out
in a storm or as the result of a car accident.
EFFECT - Catastrophic damage to hardware occurs. Data will be
lost.
Surge:
A short term increase in voltage, typically lasting at least 1/120 of
a second.
CAUSE - Surges
result from presence of high-powered electrical motors, such as air
conditioners, and household appliances in the vicinity. When this
equipment is switched off, the extra voltage is dissipated through
the power line.
EFFECT - Computers and similar sensitive electronic devices
are designed to receive power within a certain voltage range.
Anything outside of expected peak and RMS (considered the average
voltage) levels will stress delicate components and cause premature
failure.
Noise:
More technically referred to as
Electro-Magnetic Interference (EMI) and Radio Frequency Interference (RFI),
electrical noise disrupts the smooth sine wave one expects from
utility power.
CAUSE - Electrical
noise is caused by many factors and phenomena, including lightning,
load switching, generators, radio transmitters and industrial
equipment. It may be intermittent or chronic.
EFFECT - Noise introduces glitches and errors into executable
programs and data files.
