Power Quality:
Electricity is one of the most
widely used raw materials in the
commercial and industrial fields.
Since it requires continuity and
cannot be stored, any quality
assurance and supervision cannot be
ensured before use. For this reason,
the manufacturer needs to be quality
and reliable. The production of
electricity is far away from the
usage areas, the production of
several different generators in
production and the use of different
transformers and cables up to the
consumption point affect the quality
and reliability negatively.
From the consumer's perspective, the
problem is becoming quite complex.
The energy produced with the
generators without any problem
cannot be delivered to the consumer
at the quality they are produced.
Interruptions, short-term changes in
voltage level negatively affect many
users. For this reason, although the
definition of power quality can be
done at any point on the network, it
is generally important for the
consumer side. In order to define
the power quality simply, at any
point in the network, the frequency
and frequency of the voltage is to
maintain the nominal values and the
waveform is sinusoidal. Bir Bir

The non-sinusoidal current draws
from the network cause a serious
harmonic pollution in the
transmission and distribution
systems and create voltage drops in
the lines in such a way as to
distort the voltage waveform. For
this reason, manufacturers think
that sensitive consumers should take
their own quality measures by taking
costs. Producer's high quality
production and transmission for
every consumer
It is not economical. However, the
manufacturer should also prevent the
occurrence of points that may cause
problems in the network design or
determine the risky points by
estimating the risk. Freezing colds,
strong winds and lightning, such as
the result of natural events that do
not originate from the
manufacturer's natural factors can
be counted as disruptive factors and
these problems can be reduced with
the right calculations.
In order to increase the quality of
the produced energy and to produce a
solution in this direction, firstly
the causes of the poor quality
should be found, the time of their
occurrence should be determined and
various classifications should be
made according to these data. By
measuring the power quality, the
parameters such as voltage and
current changes can be recorded and
necessary precautions can be
prepared according to these
measurement results. Continuous
monitoring of the network provides
the necessary data for the
statistical analysis of the problems
occurring in power systems, and it
is possible to determine what
measures can be taken in the future.
