Types of Power Problems

and what they look like.

There are many types of power problems that can affect
the quality of the AC power being delivered to a piece of
equipment. Different types of problems will have different effects
on the operation, or even life expectancy of this equipment.
Knowing what these problems are, and what some of the
consequences are of having these problems, can help in the process
of identifying what can be done to help protect this equipment.

The following pages describe several of the more common
types of Power disturbances, and list what some of the causes are.

 Dropout - Power Failure
 Sag
 Impulse
 Common Mode Noise
 Surge
 High Frequency Noise

DROPOUT (NOTCH)

A condition where a portion of the sine wave has a lower
than expected value or is missing entirely, usually for a
portion of a cycle. These types of problems can be caused
when large motors are started, Lightning arresters are
employed (during a lightning hit), or when electrical
equipment fails. Dropouts can lead to failures in
computers and electronic equipment , reduced life of
motors and flickering lights.

POWER FAILURE

When the duration of a dropout exceeds 1 cycle it is
usually referred to as a Power Failure, or Blackout. This
problem is the easiest to observe.

Figure PT 2 - Dropout

Model OM-PQR1010

Ver 1.2 - March 2010

SAG

(UNDER-VOLTAGE, DIP, or BROWNOUT)

A power sag (or low line voltage) is a decrease in line
voltage of at least 10% of the average line voltage for half
a cycle or longer. The power sag is often caused by large
inductive equipment (e.g. photocopy, postage equipment)
being applied on the same AC line as is being tested. Sags
can be caused by external factors as well, such as large
power draining equipment used in other buildings. Sags
can be particularly detrimental to electronic equipment
because of the malfunctions caused by the sudden
decrease of available voltage to the power supply.
Complete failure rarely occurs, and often the equipment
user continues to operate the device, unaware of the
potential logic circuit problems that may have occurred.

Figure PT 3 - Sag

Model OM-PQR1010

Page 54

Ver 1.2 - March 2010

IMPULSE

(SPIKE, SURGE)

The spike is a surge of energy superimposed on the AC
line, usually with a relatively short duration. Spikes can
potentially have the most serious effects on electronic
equipment due to their high energy content, and the
Integrated Circuits inability to absorb the energy. Many
events can cause spikes, such as lightning bolts, utility
grid switching, switching inductive loads on and off, and
SCR (Silicon Control Rectifier) dimmers. Although
properly designed equipment has some built-in spike
protection, repeated hits by high energy spikes can
eventually render these components useless.

Figure PT 4 - Impulse

Model OM-PQR1010

Page 55

Ver 1.2 - March 2010

COMMON MODE NOISE

In single phase power systems, as found in many
countries such as the USA, the load (computer or
equipment) is connected between the hot and neutral
line. Usually the neutral line is connected to earth
ground at the service entrance, so that in effect the
neutral line should have 0 volts at the load. At a typical
site, voltage is induced onto the neutral line by other
equipment. This voltage can appear in the form of
impulses, or a continuous pseudo sine wave.

Figure PT 5 - Common Mode Noise

Model OM-PQR1010

Page 56

Ver 1.2 - March 2010

SURGE

(SWELL OR OVER-VOLTAGE)

A power surge is the opposite of a sag and is often
referred to as "High Line Voltage". A surge is defined as
an increase in line voltage above 128 volts (on a 115V
Line) for a half cycle or longer. Like the sag, the power
surge is often caused by large inductive loads being
applied on the same line. Power surges cause some of the
most dangerous occurrences, and their results are the most
difficult to correct.

Figure PT 6 Surge

Model OM-PQR1010

Page 57

Ver 1.2 - March 2010

HIGH FREQUENCY NOISE

High frequency noise can be caused by electronic
equipment feeding internal noise back onto the power line,
or logic induced noise from switching power supplies.
This noise is transferred to the AC line causing
disturbances greater than 2V peak-to-peak superimposed
on the AC sine wave (normal mode noise). This noise can
cause internal component degradation and eventual
system failure. During this degradation period, system
lockups, resets and data transfer will increase.
