What is a Power Quality Analyzer
A Power Quality Analyzer (PQA) is a device to measure the quality of the electrical power
network. Beside of the basic values like voltage, current and power, a PQA can measure
also values like harmonics, dips, swells, peaks, transients etc.
In an installation without a proper power quality, an electrical device/load may malfunction,
fail prematurely or not operate at all. There are many ways in which electric power can be
of poor quality and many more causes of such poor quality power.
To avoid a situation where devices and installations are faced with poor power quality, a
PQA is required. A measurement, the information and also a reaction to protect installation
is very useful and helps to extend machine lifetime.

Most common perturbations 1
•
Voltage SAG
A short voltage sag is a short-duration reduction in rms
voltage caused by faults on the power system and the
starting of large loads, such as motors.
•
Voltage SWELL
Is defined as the increase in the RMS voltage level to
110% - 180% of nominal, at the power frequency for
durations of ½ cycle to one minute. It is classified as a
short duration voltage variation phenomena.
•
Voltage SPIKE
Very fast variation of the voltage value for durations from
several ms to few micro seconds. These variations may
reach thousands of volts, even in low voltage. Caused by
lightning, switching of lines or power factor correction
capacitors, disconnection of heavy loads. The
consequences can be destruction of electronic
components and of insulation materials, data processing
errors or data loss, electromagnetic interferences.

Most common perturbations 2
Harmonics
Voltage or current waveforms with a non-sinusoidal shape. The waveform corresponds to
the sum of different sine-waves with different magnitude and phase, having frequencies
that are multiples of power-system frequency.
Causes: arc furnaces, welding machines, rectifiers, and DC brush motors, all non-linear
loads, such as power electronics equipment, switched mode power supplies, data
processing equipment, high efficiency lighting.
Consequences: Increased probability in occurrence of resonance, neutral overload in 3phase systems, overheating of all cables and equipment, loss of efficiency in electric
machines, electromagnetic interference with communication systems, errors in
measurements when using average reading meters, nuisance tripping of thermal
protections

Where is a PQA built in?
Typically a PQA is used in installations where a failure is not acceptable or
very expensive. The measurement point is normally at the entry point of the
power network. For special applications (like datacenters) several PQA’s
are placed on each server row.
Typically applications for PQA:
Datacenter application
Industrial application
Automated production lines
Advantages:
Avoid down time of production lines
Expand the lifetime of devices/machines
Avoid unbalanced power networks
Early alarming to any disruptive factor
Detect harmonics due to switch mode power supplies
Detect repetitive/cyclic disturbance on the power network (sags, swells, etc.)

PQA in industrial application
Power grid
Compressed air
Wave soldering
Punching press
CNC machine
Filter
Unit
Energy meters to measure the energy
consumption of different machines.
PQA is used at the entry of
the installation to monitor the
power quality.
A power quality measurement helps to:
Avoid down time of production lines
Expand the lifetime of machines
Avoid unbalanced power networks
