Assemble your own Portable Power Analyzer Unit at
a Low Cost
Part-1
Introduction to the project background.
It is no doubt that every Electrical Technician or an Engineer
would like to get himself well equipped with the latest Electrical
Tools and Equipment for his scope of work. Most of them definitely
will have a proper Toolkit and Meters such as a Multimeter,
Clip on Ammeter or a Megger Insulation Tester to name a few.
When one is engaged in the subject of Power Quality in the
Electrical subject, then only the above mentioned equipments
alone will not be sufficient. What he needs will be a Handheld
Power Analyzer Unit. These meters which are available gives
you all the information that is needed to analyze an Electrical
Installation to the completion on Power quality.
The Big question is can everyone afford to spend such a big
amount [ you can easily get the prices of Handheld Power Analyzer
units from the Internet ] for a Electrical metering equipment?
Of course the companies and personnel engaged in the Electrical
Power field will already must have invested on such an equipment
since it is a basic need for their work scope. There will
be thousands of others, who would need such an equipment once
in a while during his electrical installation projects. The
payback time for the investment on such an advanced equipment
might not be practical or attractive to him so he would not
consider buying such an equipment outright.
Well, there is a solution if one is good at doing little
bit of DIY type assembling or like to learn doing such things.
The cost will be very much less and the unit can be made used
to get analyzed reports to a PC using software and RS-485/RS-232
interface. Anyone with the practical touch for project building,
will realize that it is not a difficult project. It will not
be a Handheld Power Analyzer unit but can call as a Portable
Power Analyzer Unit.
It is needed to stress that,
this unit will be having 3 Phase, 400V Electrical Power when
energized. So the Safety factor is very important or let us
say " very critical" throughout. It is recommended
that only persons who are competent in the Electrical Installation
work should undertake a project of this nature and if proceeds,
will be doing it at his own risk.
Well, Electrics is not for everybody
but tens of thousands of humans are engaged in it even at
this moment. Literally speaking, there is a risk in every
small thing we humans engaged in. Well, the important aspect
is that one should realize, that there is a risk factor and
we have to minimize it by various means using our knowledge
and experience on that particular issue. That way one can
overcome the risks inherited and gain the useful dividends
that can be obtained from the same source.
