Green Energy Power!

January 3rd, 2010

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!

Rapid Growth Forecast For Ebook Reader Sector In 2010

January 2nd, 2010

Amazon has had a great year in 2009. A lot of the credit for that must go to the Kindle ebook reader family. The Kindle 2.0 and its larger sibling, the DX, have been a huge success for Amazon. The Kindle is now Amazon’s number one selling product.

At the moment, the Kindle is accounting for 60% of all ebook reader sales in the USA. The Kindle 2 recently had its global launch. Even if Amazon can’t reproduce such good figures on the international stage – though this may well be possible – the increased size of their potential customer base should be more than enough to drive even better results in 2010.

There are some who suppose that the main reason for the Kindle’s phenomenal success so far is a lack of competition. Whilst it may be true that, until recently at least, there weren’t many readers which users would have considered as a genuine alternative to the Kindle, the fact of the matter is that the Kindle was an innovative product which redefined the market and that is the primary cause of its success to date.

There are certainly enough alternative readers available today – or due for release in the near future. The long list of competitors which either have their own readers on the market or scheduled for imminent release is a clear indication of the level of growth which can be anticipated in the e-book reader market. Although the market is new and is still in development, it has received support from a variety of different sources – including the world of academic publishing and various political bodies. Rapid growth looks inevitable.

Another good indicator of the expected level of growth in this sector is the high volume of third party goods available to protect, customise and accessorise ebook readers. At the moment the majority of these items are intended for Amazon’s Kindle reader. If you want a Kindle cover, Kindle reading light or a spare charger then there are plenty of independent manufacturers ready and willing to meet your needs. The choice for new readers, such as Sony’s Daily Edition and the Nook reader from Barnes and Noble will gradually expand as their popularity increases.

2009 was a good year for Amazon and 2010 will be a good year for ebook readers in general – they will become much more commonplace. The dominant position of Amazon will certainly come under attack and strong competition will result in a downward price trend – possibly driving prices low enough for ebook readers to enter the mainstream personal electronics market.

Many business analysts suggest that $ 150 is the magic price level at which this will happen. Looking at the competition in the market, it’s not unreasonable to wonder if this price level might actually be achieved during the course of 2010.

Why Intercom Systems For Homes Are Needed

January 1st, 2010

There are 2 different types of intercom systems for home available in stores: wireless & wired.

Nowadays most people opt for the wireless save for the situation where they have a home that already maintains the wiring infrastructure, or do the job while the home is being constructed. It will cost a few dollars to get the someone install the wiring.

There are a few benefits to obtaining a wired system that you can’t have with a wireless intercom.

Some wireless intercoms may have an interference problem if you’ve got neighbors who are using their own intercom setup.

There are black spots which will come up in different rooms when you’re going with wireless.

Wireless intercom systems for homes are typically thought of as far more reliable, & if you are putting them around your home as a baby-monitoring device, you’ll want to have peace of mind about the fact that it’s secure and that your child can always be heard.

Intercom systems for home are useful for home security. You’ll be able to get the person to tell you who they are before opening the door.

How many horror tales have come about from someone allowing someone inside in naivety and encountering someone there who shouldn’t be? One could also add a video camera to the intercom if you would like to be able to see who’s out there.

Another thing you can do is to add an automatic gate entry control to your intercom device if you want. They can work on several different sorts of gates like: sliding gates, swing, single or double gates. You’ll open your gate with a single button, & know the fact that it will self lock on command.

The price of intercom systems for homes is rather varying, but a basic device can run at around $1200 for a typical 4 or five bedroom house whereas a device that distributes music will run anywhere within the range of $2500 to $5000 & higher, depending on the options you prefer.

A Short Report Of New Lg Lcd Televisions Available On General Sale At Present

December 31st, 2009

LG produce a large range of LCD televisions ranging from 15″ to 50″. The latest range of LG LCD televisions is the REGZA; the REGZA series incorporates a whole host of LG’s latest innovations which include the Meta brain and Active-Vision II.

Every TV in the LG range now comes with High definition viewing as standard meaning you get 1080p picture quality available every minute whether you want to watch a HD movie or compete in a HD game.

The Meta brain provides all of the TVs power allowing for The Activevision II and Resolution+ features to be fully utilized. Without the Meta Brain these functions would not be possible.

ActiveVision II is the picture processing unit which has won Toshiba many awards. This function delivers amazing images from either a high definition source or a standard definition source. It increases the number of colors outputted on the TV.

Resolution is aimed to try and make standard definition feeds as good as HD feeds. The feature increases the edge detail of the picture and also increases the textual content resulting in a picture almost as good as HD an impressive feat considering standard definition contains about half as much information.

Autoview is a function that automatically adjusts the backlight of the TV with respect to the ambient lighting of the room. In bright rooms the backlight is increased to make the picture more visible whilst in darker rooms the backlight is dimmed to ensure less strain on the eyes.

LG recognize that high quality pictures do not encompass total viewing pleasure and as such have included audio systems that are comparable to the standard of picture from the TVs and that are relevant for their size. Bass boost is fitted to allow for deep tones to be replayed whilst Digital out connections are provided for Digital sound.

Most of the REGZA range includes a dedicated Gamer mode. At the click of a button you can select the game mode and the TV automatically adjusts the picture settings to provide a more natural experience giving you an advantage over your online adversaries.

All of the generic connections are included on the back of the TV; Component, RCA and SCART whilst digital connections such as HDMI, PC input and Digital audio as previously discussed are also included.

The LG LCD televisions range is probably the second best in the business losing out only to the Sony Bravia range but then considering the cost of the Sony’s it’s easy to see why. Including price in the decision and personally I would say the REGZA range is the best available reasonably priced wit high quality picture and sound encased in a stylish design.

CompTIA Training Providers In Detail

December 26th, 2009

There are four specialist areas of training in a full CompTIA A+ program; you’re qualified as an achiever in A+ when you’ve passed the test for just two specialist areas. Because of this, it’s usual for colleges to limit themselves to 2 study areas. The truth is it’s necessary to have the information on each subject as industry will ask for an understanding of all four areas. You don’t have to complete all 4 certifications, but it seems common sense that you at least have a working knowledge of every area.

A+ certification without additional courses will set you up to mend and maintain stand-alone PC’s and MAC’s; ones which are usually not part of a network – which means the home or small business market.

If you would like to be a man or woman who works for a larger company – fixing and supporting networks, build on A+ with Network+, or consider an MCSA or MCSE with Microsoft to give you a wider knowledge of how networks work.

Students will sometimes miss checking on something of absolutely vital importance – how their training provider divides up the physical training materials, and into how many separate packages.

Drop-shipping your training elements piece by piece, according to your own speed is the usual method of releasing your program. Of course, this sounds sensible, but you should consider these factors:

It’s not unusual for trainees to realise that their training company’s standard order of study isn’t ideal for them. You may find that a slightly different order suits them better. And what if you don’t get to the end inside of the expected timescales?

For future safety and flexibility, it’s not unusual for students to make sure that every element of their training is posted to them in one go, with nothing held back. That means it’s down to you how fast or slow and in what order you’d like to take your exams.

We’re often asked why qualifications from colleges and universities are being replaced by more qualifications from the commercial sector?

As demand increases for knowledge about more and more complex technology, the IT sector has been required to move to specific, honed-in training only available through the vendors themselves – in other words companies like Adobe, Microsoft, CISCO and CompTIA. Frequently this is at a far reduced cost both money and time wise.

Many degrees, for instance, often get bogged down in too much background study – with a syllabus that’s far too wide. Students are then held back from understanding the specific essentials in enough depth.

Put yourself in the employer’s position – and you wanted someone who could provide a specific set of skills. Which is the most straightforward: Go through a mass of different academic qualifications from hopeful applicants, having to ask what each has covered and which vocational skills they’ve mastered, or pick out specific commercial accreditations that precisely match your needs, and then select who you want to interview from that. You’ll then be able to concentrate on getting a feel for the person at interview – rather than establishing whether they can do a specific task.

A service offered by some training providers is a Job Placement Assistance program. It’s intention is to help you find your first job in the industry. However sometimes there is more emphasis than is necessary on this service, for it is genuinely quite straightforward for any focused and well taught person to get a job in the IT industry – because there’s a great need for qualified personnel.

Having said that, it’s important to have help with your CV and interview techniques though; also we would encourage everyone to get their CV updated the day they start training – don’t procrastinate and leave it for when you’re ready to start work.

A good number of junior support jobs have been offered to students who are still studying and haven’t got any qualifications yet. This will at least get you into the ‘maybe’ pile of CV’s – rather than the ‘No’ pile.

If you’d like to get employment in your home town, then you may well find that a local (but specialised) recruitment consultancy can generally serve you better than the trainer’s recruitment division, due to the fact that they’re far more likely to know the jobs that are going locally.

Many men and women, it seems, are prepared to study their hearts out (for years sometimes), only to give up at the first hurdle when looking for a good job. Promote yourself… Do your best to get yourself known. Don’t think a job’s just going to jump out in front of you.

Traditional teaching in classrooms, utilising reference manuals and books, is often a huge slog for most of us. If you’re nodding as you read this, dig around for more practical courses which feature interactive and multimedia modules.

Studies have time and time again verified that connecting physically with our study, is much more conducive to long-term memory.

Start a study-program in which you’re provided with an array of CD and DVD based materials – you’ll start with videos of instructor demonstrations, with the facility to fine-tune your skills in fully interactive practice sessions.

Every company that you look at should be able to show you a few examples of the materials provided for study. You should hope for instructor-led videos and a wide selection of interactive elements.

Seek out CD and DVD ROM based physical training media wherever available. Thus avoiding all the issues associated with the variability of broadband quality and service.

Names Of The Latest Cisco Router Emulation Software Packages

December 21st, 2009

Computer networking students are caught in between a rock and a hard place when going through difficult course studies. Students need access to hardware available in class to do labs and reports, and may not have the same hardware at home to work on. Emulation programs have sought to fix this problem.

An expensive yet thorough solution is with Boson’s software packaged named Netsim. Netsim ranges in value, from $200 to $500, depending on the licensing and options needed. Netsim is the best bet for instructors, as it comes loaded with plenty of extras such as activities and grading programs. Perhaps less affordable for students, who are usually on a tight budget.

Open source programs should receive the attention of students since they are free to download and use. Dynagen is one such program, of which is built with the Dynamips simulator. Dynagen is one of two software packages that currently works with Dynamips, and is often described as being the less friendly of the two. Documentation is also lacking for those with questions.

GNS-3 is another program based on the Dynamips emulator. GNS-3 is more popular among beginners since it has a better interface and better support. GNS-3, or Graphical Network Simulator, has a developer’s forum and video tutorials to get students ready to use the program. It may not have key features that Netsim has, but teachers can still issue this free program to students and have take-home assignments for them to complete.

Self-learners are a breed of students that don’t need classes to obtain their certifications. Although they may be saving money on course costs, they won’t be able to use the best network simulator to date: Packet Tracer. This program is produced by Cisco, who took the time to make the interface amazingly simple to use for such a powerful program. Packet Tracer isn’t available for download to the public, yet if you are alumni or a current student you can access the download area.

There are several web-based programs used with Macromedia Flash and text-based applications that one can look at. These range from free to pricey, just as standalone programs do. Web-based applications can be just as useful, but keep in mind you’ll have to have a constant connection to the Internet to use most of them. Often times it’s just better to get a desktop application for ease of use.

Closing Comments

Network simulation is advanced technology. Thus, there aren’t too many choices to dwell on while you are looking for a study aid. Check those mentioned and perhaps do some searching of your own to see if updates or new programs are on the horizon.
