Good day electrical brethren,

I am currently working as a Facilities O&M in a semiconductor industry. I've been tasked to be the Power Quality system owner. I would like to seek help about things to be done like:

specifications of parameters
programs (monitoring and maintenance)
tools to be used (hardware and software)
SOPs
tips and advise.
actual experience

thanks
 
Do you have any background in PQ?

Not that you can't learn it, but seems a lot to bite off at once. Just owning the tools and software will not give you the knowledge to understand everything involved. It just seems a firm like you seem to be discussing might have a few engineers on retainer to assist?
 
The Semiconductor industry is very large and has their own set of particular standards called SEMI Standards.
here is one reference. You can see they have a committee on facilities that might be helpful to you.

http://www.semi.org/en/Standards/P_000787

I worked, designed and maintained equipment for use in that industry for many years and their requirements for power quality are more stringent than a lot of other industries.
 
be aware of the power quality standards prevailing in your area. your POCO follows a set of PQ standards and you should be able to match them with the PQ requirements of your equipment. having equipment that wont match with the POCO standard means trouble.

so mr robbie tan, the owner/movie producer of seiko films is also an electrical practicioner. :D

It's not so difficult to monitor power quality. A number of members have suggests instruments and methods of collecting data.
How you interpret that data and what you do with it is maybe where the expertise and experience comes in.

In UK and probably elsewhere the simple rule is that you may not do anything to the supply that affects others connected to that supply commonly known as the point of common coupling. But, given that we all have some non-linear load, we all do. In recognition of this, there is an Electricity Association engineering recommendation, G5/4, which sets out maximum levels levels of harmonics, both current and voltage, up to the 50th harmonic the various voltage levels of the distribution system.
I think US has something similar - IEEE 519 - possibly with different limits.

However, giving limits doesn't tell you how to meet them and there is no "one size fits all" solution. An instrument will give you data. I generally use a digital storage oscilloscope and download collected data to a PC. With a bit time domain and frequency domain analysis, and the patience to do it, you can get to a workable solution.

am registered electrical engineer in the philippines. since you know the (in)famous robbie tan, I suspect that you are in the same area. why not send me a PM so we can help each other out?
