Buyer Beware – Using Power Factor Correction and Transient Voltage Surge Suppression to Reduce Energy Costs.

Today’s energy conscious climate has motivated many to do what they can to become more efficient and conserve energy and money. Unfortunately this same climate has prompted others to take advantage of unsuspecting consumers’ wishes to save energy and reduce expenses.

Companies that tout power factor improvement (kVAR correction) and transient voltage suppression are a good example of this bad trend. Lately we are seeing more and more of these companies cropping up and feel it is time to set the record straight.

First, transient voltage surge suppression (TVSS) plays a valuable role in improving power quality to protect sensitive equipment inside a facility. However, TVSS does not save energy. TVSS’s are only active a tiny fraction of a second to protect against voltage surges which only last for less than a millisecond. To actually reduce energy consumption the TVSS would need to actually cut power consumption for an extended period of time which is not what they are designed to do. Again, TVSS is important to protect sensitive electrical equipment but buyers should avoid vendors promising, or even guaranteeing, that they will reduce energy consumption.

Now what about vendors who claim that improving power factor will save 15% or 20% or 30% of energy consumption and corresponding cost? This one is a little trickier.

For residential applications, power factor does nothing to save energy because the typical home already has an average power factor of about 0.97 which is almost the perfect power factor of 1 or unity. In addition, the device (called a capacitor) is placed at the main circuit breaker. According to IEEE 5.5.3.3 capacitors must be situated at or near the respective inductive loads to reduce power system losses by reducing heat and distribution losses known as I2R losses.

So what about commercial and industrial facilities using power factor correction to reduce energy costs? It is perfectly appropriate for a company that is incurring penalties or a kVA billing structure from the utility company to improve the facility’s overall power factor by employing a capacitor bank at the main service entrance or individual capacitors at or near the respective motor loads. Doing so will eliminate the power factor penalties and/or reduce the kVA demand charges on the utility bill which can save significant money and provide a significant ROI on the investment.

But what about power factor correction reducing kWh consumption? IEEE also tells us that I2R losses only account for 2 to 5% of the total load in a facility. Simple math tells us that it would be against the laws of physics to get the 15% to 30% energy reduction claimed by some vendors. Think about it. Even if your facility had 5% distribution losses and you could correct 100% of the problem via power factor correction at every load (which can’t be done) you would still only save 5% at the most. No where near the claims of some capacitor vendors and manufacturers.

All that said, power factor correction when done properly will eliminate utility penalties and kVA demand charges, improve facility power quality, increase electrical system capacity, and save a little energy when applied to the appropriate motor loads.

So make an investment in transient voltage surge suppression and power factor correction when appropriate and necessary. But caveat emptor!

Should you want a career in supporting networks then the Microsoft Certified Systems Administrator course is the ideal one for you. So if you want to get started in the industry or already have knowledge but want a professional course, a number of options are available to help you either way.

To pass at the MCSA level you need to pass 4 Microsoft Certified Professional exams (MCP’s). If this is your first entry into computing exams, it’s likely you’ll be required to learn a few things prior to tackling the first of the four MCP’s. Look for a company that has a team of advisors who can help you sort out the ideal program for you and who will get you started in the right place.

Massive developments are coming via technology in the near future – and it becomes more and more thrilling each day.

Computer technology and interaction through the web will noticeably change our lives in the future; profoundly so.

The average IT technician in Great Britain can demonstrate that they earn a lot more than his or her counterpart in another industry. Average wages are amongst the highest in the country.

As the IT industry keeps increasing nationally and internationally, it’s predictable that the need for certified IT professionals will continue actively for the significant future.

It’s essential to have an authorised exam preparation system included in your course.

Because most IT examining boards are from the USA, you need to become familiar with their phraseology. It’s no use merely answering any old technical questions – they need to be in the proper exam format.

Ensure that you check how much you know by doing quizzes and practice exams before you take the real deal.

Trainees looking at this market are usually quite practically-minded, and aren’t really suited to the classroom environment, and struggling through thick study-volumes. If you identify with this, use multimedia, interactive learning, with on-screen demonstrations and labs.

Long-term memory is enhanced when we use multiple senses – experts have been clear on this for years now.

Top of the range study programs now offer interactive CD and DVD ROM’s. Real-world classes from the instructors will mean you’ll find things easier to remember via their teaching and demonstrations. Then it’s time to test your knowledge by using practice-lab’s.

It’s imperative to see the type of training provided by your chosen company. Be sure that they contain full motion videos of instructors demonstrating the topic with lab’s to practice the skills in.

Avoid training that is purely online. You want physical CD/DVD ROM course materials where obtainable, so that you have access at all times – ISP quality varies, so you don’t want to be totally reliant on a quality and continuous internet connection.

Most of us would love to think that our jobs are safe and the future is protected, but the likely scenario for most jobs around the UK today seems to be that the marketplace is far from secure.

We can however discover market-level security, by searching for high demand areas, together with work-skill shortages.

A rather worrying UK e-Skills study showed that over 26 percent of all available IT positions are unfilled mainly due to a huge deficit of appropriately certified professionals. So, out of each 4 positions available across IT, employers are only able to find trained staff for three of them.

Achieving in-depth commercial IT accreditation is consequently a quick route to achieve a life-long as well as satisfying occupation.

In reality, acquiring professional IT skills over the coming years is likely the best career move you’ll ever make.

Are you trying to raise capital for your start-up or corporation in expansion? Have you exhausted your traditional institutional sources and hedge fund contacts? Don’t lose hope just yet! First of all, take all those pamphlets and brochures from banks and other traditional lenders that are lying all over your desk and toss them in the trash…they are absolutely useless.

Banks don’t have your company’s best interest in mind as they are hardly even staying afloat in this economy. Today’s institutional financier isn’t qualified to run a bath let alone a bank. Don’t put your future in the untested hands of a 20 something knucklehead. After you’ve tossed all that useless info in the trash, clear your head and then look at your company and ask yourself a few tough questions: Is your company invest-able? Do you and your executive staff have a pedigree that investors deem as seasoned enough to take their money and make affective use of it and not lose it? What proprietary concepts/technology/patents do you have that give you a larger market share with the proper cash infusion? What is your current capital/debt situation?

If, after pondering these questions you’ve come to the conclusion you honestly, truly have something worth pursuing then the next step is to look at the reality that your company is worthy of a public offering. Stay away from Pink Sheets and be weary of reverse mergers and in reality your company won’t qualify for the NASDAQ so the quickest way to raise public capital is the OTCBB (over the counter bulletin boards).

OTCBB is an SEC regulated platform that has a solid investor following and market makers that can effectively promote your stock to rapidly raise capital. Don’t let these difficult economic times steal your dreams of corporate prosperity and personal growth.

If you have a solid business concept, there is a way to fund it. Look into the OTCBB, it’s your best bet for an inexpensive public offering with a direct path to long term funding.
