The end of 2009

This year has been a trying one for many people and companies including us. We have had some nice projects that we have worked on and business has not been as bad as most others we hear about.



As for all the talk about the “Going Green” movement, it hasn’t really amounted to much for us even though we offer a wide variety of products for cutting cost and conserving energy. Most just don’t seem to want to spend the money to save money, which is a bit strange to me.



Lets look at it this way:

Your home utilities cost you $3600.00 per year. Someone knocks on your door and offers to save you half on your utility bills ($1800) if you would pay him $500.00 right then, would you do it? If you didn’t you would be crazy! This year you would save $1300 and next year you would get a savings of $1800, what a great thing you have been offered.



The same thing goes for business but not many want to do it. Purchasing certain products for our places of business can result in great returns on investment yet most don’t take advantage of them. Just like training your people, you spend the money to send them to factory (and other) training hoping to get a return on that time and money with increased sales, no?



Enough about that.



We recently sent Madhu to Shreveport Louisiana to do some work on an oilrig. He found the problem and was able to get them back up the first day on site. The company is one we have done work for in the past. They use a 1500 horsepower VFC to run the hoist for the drill pipe on the rig. Needless to say, they were very happy to get back to work.



We started up some VFC’s we had built for the JC Penney’s building, which is part of the City Creek project in downtown Salt Lake. These were Siemens drives we built-up with bypass for Siemens and were sold through Codale in Salt Lake City.  They are running the air-handlers for climate control in the building.



The start-up is now complete on the Sandy City Granite Tank project, which is located just below the mouth of Little Cottonwood Canyon. This project has three 125 horsepower US Drives mounted in a Siemens Motor Control Center with other associated equipment.



We just completed the equipment for Herriman City’s new pipeline and tank project and also a big Siemens Motor Control Center for Timpanogas Special Services District for the Boat Harbor Lift Station. These projects will be installed over the coming weeks.


Please continue to check out the products that are listed on the site.  We have some new products that I am very excited about and we are adding things all the time.  If you need a manual for a product, it can be found under the specific vendor on the site.  If you find that it is not there, contact me and I will make sure and get it added.


Hopefully for all, 2010 will bring more hope and prosperity than this past year.  I tend to be a "Glass half full" person but it has been tough to keep that attitude in this ecomomy.  Things need to change for the better and I'm sure they will if we can better control our representitives.  It just takes a minute to email your Congressman or Senator and give them your opinion.  I do it all the time and if nothing else, it makes me feel better!  In the words of Jack Nicholson as the joker, “What this town needs…is an enema”. I think the country is in need of that but who am I to say. JMHO

Thanks to all of you that have supported us over the years.  We will continue to do our best to earn your business throughout the coming year.  By-the-way, this year is our tenth year.  We could not have made it here without you.

Thanks again,

Scott

October Activities

This month has been a busy month for Power Quality Monitoring.  I have done studies at two different facilities and have two more to do before the month is out.
So far, nothing very unusual to talk about.  Mid-level Harmonics causing some nuisance problems on signal cables coupled with RFI coming from long output leads from Variable Frequency Controllers.  The RFI can be solved with an output filter in most cases as was the case at one of the locations.

At another site the customer has a couple of Siemens 4300 power meters that have not been working.  These were programmed for PT inputs and are actually connect directly to the 480 supply.  They also read in negitive numbers.  This is due to the Current Transformers being installed upside down.  This happens all the time as most don't know that most CT's are directional.

We finished a Motor Control Center with VFC's for a project in the new Downtown "City Creek" Center.  I will post some pictures of this on the website as soon as I can.  Nothing special, just a nice job.

Madhu flew to Indonesia to work on a VFC on an Oil Rig in the ocean.  He fixed it the first day he was on site.  It seems that the customer had reinstalled one of the plugs on the drive incorrectly and cause a failure of the power supply.  While there, he has been doing some training for the people that work the oil rig.  He also will fly home to visit with family as he is not far away from India prior to coming back to Salt Lake City.

Looking forward to what November has to offer.  Some big things in the works but we'll have to see how they all play out.

Transient Voltage Surge Suppressors

There has been a change in the way TVSS's are being tested now by the addition of new specification required by UL 1449 3rd Edition.  Measured limiting voltage testing is now preformed at 6kV/3kA.   Also, this test is now an ANSI standard which has not been the case in the past.

There has also been a change in the terminology from Transient Voltage Surge Suppressors to Surge Protection Devices.

There has been the addition of Nominal Discharge Current to ratings and markings on the devices.

This testing now includes Duty Cycle testing at nominal discharge current.

UL 1449 3rd Edition also gives four designations to surge protective devices (SPD's) depending on where in the electrical system the device is connected.

Type 1 - Permanently connected device installed before of after the service disconnect overcurrent device and intended to be installed with no external overcurrent protective device.  This type of SPD most closely relates to devices tha were called secondary surge arrestors prior to 3rd Edition.

Type 2 - Permanently connected device installed after the service disconnect overcurrent device.  This type of SPD most closely relates to devices that were called transient voltage surge suppressors prior to 3rd Edition.

Type 3 - Point of use SPDs that are installed with a minimun of 30 feet of conductor length from the service panel.  These 30 feet of conductor lenght does not include conductors used to attach the SPD.  Some examples of Type 3 SPD's are cord connected, direct plug-in and receptacle type SPD's.

Type 4 - Component SPD's and component assemblies.

There is quite a bit of information about this that can be found on the web.  If you want to know more about the testing, do a Google search and UL 1449 3rd Edition and several good articles can be found.  EC&M has a great article on this and Eaton does as well.

The point of this is that all manufacturers must now meet this testing with the product they are producing at this time.  They still can sell all the product they have produced prior to this going into effect on 9-29-2009.  Some manufacturers were building in fuses to meet the 2nd Edition criteria which was a cheap way of getting around it because if the fuse blows your protection is lost and most times you don't know about it.

TPS has met the new standards and is still the leading manufacturer for the best and most reliable TVSS/SPD's on the market.
