Understanding Transformers

Posted on by

What does a transformer do? Transformers form a way control voltage. They take voltage and either step voltage down, step voltage up or isolate voltage in one area from another. So why is it so important to control this voltage. Take for example your local power company. It uses a step up control transformer to give high voltage to the power lines which creates low amperage. Then before entering your home or local business steps the voltage back down so the voltage entering is not excessive.

What parts make up a transformer? A single phase transformers is made up of a three main components; the laminated iron core, primary and secondary windings. The primary winding is connected the power entering the transformer (input voltage). The secondary winding is connected where the power is going to (output voltage). The laminated core is used to separated the primary and secondary windings from have any physical connection.

So how do transformers work? There are no moving parts of a medical transformer, instead a transformer uses induction to pass electricity from the primary winding to the secondary winding. Easy way to understand what induction is it uses a electromagnetic force to take the voltage from the primary winding and move it to the secondary winding. We control induction with turn ratio.

What is a turn ratio? A turn ratio is the relationship between the primary and the secondary winding. If there was 120v entering the transformer and 24 volts leaving the transformer. Our voltage would be stepping down with a 5/1 turn ratio. Simple math is used to calculate this; voltage entering / voltage leaving the transformer. With 120 / 24 you would have 5/1 ration.

How do you size a transformer? You size a transformer for secondary winding of a transformer. The secondary winding is rated in VA (volts times amperage). An example of this would be you have a 24v control circuit thats capacity is 2amps. You would take your voltage (24v) and multiply it by your maximum amperage (2amps) which would be 24 times 2, which equals 48 or 48 va. This means you would need a transformer rated for 48va.

Do transformers need to be serviced? No, with no moving parts there is no maintenance required. Once a transformer has gone bad, which will general show on the primary windings, it will need to be replaced. Some transformers come with a fuseable link, or a safety. If a transformer has been tripped or has gone bad, it is a general rule to search for a source causing the problem. A bad transformer is never “the problem” only a symptom of the real problem.

What are the different types of transformers? There are many types of transformers you will see in the field; step up, step down, isolating, multi tap and autotransformers. There are also another type which is a three phase transformer, this transformer pertains more to voltage entering a commercial building. As a general rule the most common type of transformer you will see is a step down transformer (control voltage).

What is the difference in these types of transformers? Step up transformers take the primary winding and step the voltage up for the secondary winding. Step down transformers take the primary winding and step is down for the voltage on the secondary winding. Isolating transformers have the same voltage on the primary and secondary. A multi tap transformer is a step up or down transformer that has multi taps on either the primary winding or secondary winding. An autotransformer is a special types of transformer which does not follow common rules of transformers. It uses a continuous winding that is tapped to provide a step down or step up function.

Transformers play a key role in AC powered systems. They are a way to control voltage. There is no maintenance required to transformer though they are excellent indicators of problems. Understand these terms and principles is key to troubleshooting and designing electrical circuits.

12 Easy Tips for a Blissful Relationship

Posted on by

One of the most common questions we hear is, “How do we make our relationship work?” The answers are complicated, varied, and, after a while, can start to sound like muddled platitudes. But these commonplace sayings get repeated because they work. With this in mind, we pulled together 12 cliches that, in fact, reveal simple, tried-and-true advice for having a healthy, happy relationship. Read on and let us know what you think:

1. Mind your manners. “Please,” “thank you” and “you’re welcome,” can go a long way in helping your partner remember that you respect and love him and don’t take him for granted.

2. Variety is the spice of life. Studies have shown that dullness can lead to dissatisfaction with a relationship. Trying something new can be as simple as visiting an unfamiliar restaurant or as grand as a backpacking trip through Sri Lanka. Discoveries you make together will keep you feeling close. Video Advice: My Wife Won’t Tell Me Her Fantasies

3. The couple that plays together, stays together. Find a sport or hobby that you both love (no, watching TV does not count) and make that a priority in your relationship. Camping, biking, building model trains… whatever it is, find something you enjoy doing together.

4. Fight right. In order to have productive arguments, keep these rules in mind. Don’t call your spouse names. When things get really tough, take a break from the argument. Let the other person finish his/her sentences. Don’t initiate a discussion when you’re angry.

5. I’ll scratch your back if you scratch mine. No one likes demands (unless you’re in a BDSM role play), but everyone can appreciate a compromise. If you want your lover to do something and you’re not sure he’ll be agreeable, the quickest way to avoid a confrontation is to sweeten the deal. For example: “Sure, I’ll watch Monday Night Football if you take me to see the next movie of my choice.”

6. Two heads are better than one. Being in a relationship basically means you’ve made a merger; you’ve not only joined assets but inherited the other’s problems as well. Rather than looking at his problems as merely his own, tackle them together. For example, if he’s gaining weight, rather than pushing him to diet on his own, enroll in an exercise program together. Fun And Free: The Exercise Date

7. Distance makes the heart grow fonder. Maintain your own friendships and occasionally have a night out without your significant other. Doing things without your s.o. not only makes you miss him or her, it also keeps you sane. And, in case the relationship doesn’t work out, you’ll still have your friends.

8. Sound it out. It other words: communicate! Talking out the tough subjects-money, religion, fidelity, raising kids-will not be the most fun you’ve had, but it’ll be valuable.

 

9. Laughter is the best medicine. Learn to laugh at yourself and at silly mistakes. If he throws your $300 cashmere sweater in the dryer, laughing it off is, in the long run, better than getting angry. It’s is just a $300 cashmere sweater, not the end of the world.
10. Keep your eyes on the prize. Yes, he forgot your co-worker’s name for the tenth time, but it probably doesn’t mean he doesn’t care about you. If you keep your perspective fixed on the goal-to be in a happy, functioning partnership-you’re less likely to get tangled up in every minor annoyance. Remember, you both want the same thing.
11. Quitters never win. Find a ritual and keep it alive, no matter what. Whether it’s always kissing each other good night, renewing wedding vows every year, sleeping in as late as you want once a month or committing to having sex once a week, pick something that makes you both feel good and stick to it, even when you’re tempted to skip.
12. When the going gets tough, the tough get going… to therapy. Studies show that couples who seek counseling during rocky periods are more successful in resolving their issues than those who don’t. Whether its from a religious figure, counselor or mental health professional, getting an expert to help sort out strife is as wise as forgoing self-installation and hiring a plumber to put in a new sink.

Scratch Weddings Finds the Perfect Match in 2012 Wedding Trend: DJing at your Own Wedding

Posted on by

To all the couples who got engaged over the holidays, the wedding countdown has begun. And, if you’re getting hitched this year, you’ll want to give extra thought to the DJ you hire. According to the most recent Wedding Entertainment Report (published by The Wedding Report, Inc.), an overwhelming 80 percent of wedding guests say the element they remember most about a wedding is the music.

One of the hottest trends in weddings today is spinning, and we’re not talking about grooving on the dance floor or indoor cycling. Today, couples are hiring top DJs, not just to work their wedding, but to show them how to do some mixing and blending of their own.

Chalk it up to the fact that the music-savvy iPod generation is now getting married or the popularity of the television show Glee or the growing celebrity culture of DJs. Whatever the reason, today’s weddings have become definite DJ performance zones.

Michelle Eckert , 33, from Los Angeles , was married last October at the L’Auberge Del Mar in Del Mar, California , and the music was top on her list.

”We wanted our wedding to have the vibe of a real club. What better way to enhance the club style than by offering guests the services of a marquee-level DJ and taking our own turn behind the turntable?” says Michelle. “DJ Mylar from Scratch Weddings  fit our vibe completely and, with his help, and a few classes at the Scratch DJ Academy in Los Angeles , our vision for our reception was transformed into a perfect reality.”

Scratch Weddings and the Scratch DJ Academy are both part of Scratch Music Group, the nation’s leader in DJ booking, technology and education. The company offers more than 700 diverse marquee-level DJs nationwide and has Academies in New York , Los Angeles and Miami.

“I was excited to take a few classes with Michelle at the Scratch DJ Academy so we could perform our own personal mix-up at our wedding for our friends and families,” says Michelle’s husband, Seth, 34, a medical device representative.

“We loved working with Hapa [Director of the Scratch Academy in Los Angeles ], who taught us the basics of working a turntable and scratching into a song. Then we picked the songs we wanted to scratch to at our wedding and practiced and practiced leading up to the big day. I scratched to Vanilla Ice’s ‘Ice, Ice Baby’ and Michelle scratched to ‘One More Time’ by Daft Punk. It was a huge hit.”

Lindsay Goldstein-Hawkes , 28, is a NJ-based newlywed who got married last year in a lavish ceremony that was featured in Manhattan Bride magazine. Now, she’s helping her sister, Chelsea, a music lover, plan her wedding.

”I just heard about Scratch Weddings and suggested Chelsea check them out,” says Lindsay. “I wish I’d known about them when we got married. I love the idea of doing something fun and special that bonds you and your partner leading up to and on your special day.”

Rob Principe , the founder and CEO of Scratch Music Group, reports that his wedding business has grown significantly over the last six months.

“Couples getting married today are very savvy about music. They want more from their wedding entertainers, expect more and deserve more. That’s why we’ve been so successful. We have the largest team of highly-skilled, professional, but still affordable, marquee DJs in the country. We spend a lot of time pairing couples with DJs who match their musical tastes, personal style, and vision for their wedding day. When it comes to your wedding day, we know that choosing your DJ is second only to choosing your mate.”

The spin-at-your-own wedding trend isn’t all that surprising when you consider that the WeddingChannel.com , the top wedding registry website, says the key to a successful wedding is surprising your guests with unexpected entertainment.

”At our wedding, we amused our guests with a signature cocktail called the Quintinni that was named after our puppy, Quinn,” says Michelle. “But we surprised our guests by spinning. So many people told us later that it was a real ‘Michelle-and-Seth moment’ that they’ll never forget. In my opinion, that’s what great wedding memories are all about.”

Your Guide to Battery Types

Posted on by

Every mobile electronic device we own runs on battery power, yet we take batteries for granted – at least until they run out of juice. No matter what kind of device battery – laptop battery, cell phone battery, camcorder battery, remote control battery – you need, it’s helpful to know the various kinds of battery types and their uses.

Gel Battery – A gel battery is also known as a sealed lead acid (SLA) battery, and its distinguishing feature is that it doesn’t have to be kept upright in order to work. An SLA battery continues to perform in extreme conditions, such as hot temperatures, or under vibration. SLA batteries are often used in wheelchairs, scooters, and uninterruptible power sources. It’s best to keep an SLA battery charged, or to charge it more often than you would other types of batteries.

NiMH – NiMH stands for Nickel Metal Hydride and is the battery of choice for many cell phones, camcorders, digital cameras, GPS systems, PDAs, and other personal electronics. NiMH batteries are also used in hybrid cars. An NiMH is a rechargeable battery that is similar to a nickel cadmium (NiCd) battery, but that has double or triple the capacity of a NiCd battery. It’s best not to overcharge NiMH batteries.

NiCd – NiCd stands for Nickel Cadmium, and is a type of rechargeable battery commonly used in toys, electronic devices, and power tools. Although some people prefer NiMH batteries to NiCd batteries, a NiCd battery provides virtually the same level of voltage throughout its lifetime, and costs less than an NiMH battery.

LiION – LiION stands for Lithium Ion, and is one of the newest rechargeable batteries. Although they are more expensive than other types of rechargeable batteries, LiION batteries have more capacity and are often used in wireless phones, camcorders, and notebook computers. The downside of LiION batteries is that the length of their life commences from the date of manufacture, rather than from the number of times the battery is charged and discharged. It’s best to regularly charge LiION batteries and store used batteries in the refrigerator. (Allow them to warm to room temperature before using them, though.)

Alkaline – Ultra Alkaline Battery is not rechargeable with a battery charger, but offer a large current over a long period of time. These batteries are often used in CD players and portable radios.

Carbon Zinc – Carbon Zinc Battery is known for their reliability over long periods of time in low-drain situations, such as for garage door openers or clocks. AA Carbon Zinc Battery is not rechargeable.
