Welcome everyone this is Abdur Rehman
GeneralPAC by AllumiaX and in this topic
we're going to talk about the importance of power quality in the power system
electricity with bad power quality is dangerous
and uneconomical at both utility
and the consumer end
power quality can have a big impact on the performance
and the cost of the power system right
on the utility end you know they have to condition
power very very carefully and make sure that the power
delivered to all of their gaming machines
is very smooth and it's at the rated voltage and current
and frequency that the electronic devices
expect everyone has a role to play when it comes to power quality
so on the utility side they are responsible
for power quality on three ends
on the generation transmission and distribution
now think about this
the power system is
is comprised of lots and lots of generators
are connected together to serve load
consumers contribute to a big chunk of power quality
issues so this non-linear is this
key thing key driver for power quality
and that's really important and then there's equipment
sensitivity of an equipment may cause power quality issues if it is incompatible
with the electrical environment too due to high sensitivity
so manufacturers have to make sure
that their equipment is sustains these types of disturbances that might occur
on the electrical power systems
transients can come from either internal or external sources
transients although is part of power quality
it is a way to kind of part of describing
you know poor or good power quality
it's not always the point of emphasis
reduction in rms voltage
is another factor which is caused by starting of large motors
single line to ground faults
load shifting or energizing heavy loads
and this also makes sense I mean if we're in an industrial
plant for example or even like a compressor at home
or even like a microwave right as soon as we
turn on that heavy powered you know equipment then sometimes
we see like our voltage or our lights kind of dim down and then come back up
right
such imbalances voltages may harm or damage electrical
equipment that's causing poor power quality
so on the utility side very common to have unbalanced voltages
voltage magnitudes i would say
the angles is relatively 120 degrees right
flickers are the continuous variation in voltage supplied power
causes a rapid fluctuation and load currents
leading to instability of visual sensations
right it's like a CRT monitor the old CRT monitor if you
reduce the frequency of the CRT monitor
you can see it flicker you could see the screen behaving differently
these distortion can be different
types like dc offsets harmonics and electric noise
these distortions are like its own wave that's put on top of the
AC waveforms right
by the way this right here is
such a key paragraph to really hone in on
the power quality of the power system
is inversely proportional to thd we're measuring
how much harmonic content we have in comparison
to the fundamental frequency
power factor value closer to 1 indicates high power quality
as much the value the power factor is lesser than one
power factor is a component of power quality
but again it's not emphasized as much as harmonics
frequency of the power system deviates from the fundamental
value if there is an imbalance between
generation and demand
as you know as soon as we generate electrons it must be consumed
because electrons flow at the speed of light
now there are harmful impacts support power quality
on both the utility side as well as the consumer end
and some of the main effects of
poor power quality in the power systems are the following
so the point here is that harmonics and
power quality or
poor power quality is not good for the system
not good for both the utility side
not good for as well as the consumer side
and IEEE has a number of different standards some of them
are specifically related to power quality others have chapters or components of power
quality within them there's the nema mg1 motors
and generator standard for technical specification
used by manufacturer to achieve power quality
this isn't that deep analysis and monitoring
of the power quality is carried out to enhance or maintain the power quality as per the system
required you know there's an input to it and then
there's an output so input is poor power quality
output is a conditioned better power quality
so power condition devices are used to improve the
power quality that is supplied to the equipment power system
there are a number of devices that
act as power conditioning in different ways whenever
there's a rapid increase in voltage
surge protector detects such increments
in magnitudes and limit the voltage levels
sometimes there are very big devices very expensive
that are on the power lines on
the utility side sometimes there are really close
to the industrial commercial space near
the service entrance of the facility quality
is to collect analyze and use electrical data to improve
the power quality and the system performances
if you have like a generator in the presence of
poor power quality and you let that go that's a huge
impact on your generation equipment so at
AllumiaX we aim to provide a high quality power system studies
in compliance of a lot of different
standards and we just talked about a number of the standards
previously and of course we ensure
that power systems are safe reliable operable maintained
and well protected and designed so
that's us if you need a power quality study
each out if you need more further support reach out
if you have questions reach out and
thank you for joining me in this video blog this
was a very long video blog but I hope
that some of my interpretation and experiences
helped with understanding this topic
a little bit more right it's always you know I actually feel like
sometimes you know when when instructors
digress and start talking about their experiences
or problems that they've encountered or
kind of digress and go into that particular statement
right that students get a lot more out of it you know
professionals get a lot more out of it
hopefully these videos are helpful if you found it helpful
you can leave a comment and let us know
but thank you very much
and we'll see you in the next video blog take care.
