Techniques for Power Factor Enhancement
February 25, 2018
Electrical energy companies require large power users to have their energy use above a certain limit. This requirement is not the sole reason as to why large corporations should engage in power factor improvement. Having the right level of power factor ensures that a firm gets the most efficient use of power out of all their electrical appliances. Therefore, the right power factor saves cost and contributes to a sustainable earth where energy is put to proper use. As an electrician or organization that enhances power factor for example Westline Electrical Services, the choice of methods to improve the power factor will be guided by the particular application being used in your field of work.
This method focuses on removing the unnecessary baggage at the input signal called harmonics. These harmonics are located in multiple areas of the line input frequency. Therefore, the filter can be built as a cut-off a just above the line frequency to achieve only the acceptable current. In this manner, the power factor will be enhanced. This technique works best with non-linear loads.
Using A static Capacitor
This method is most effective in fields with machines that use electric motors. Most of these machines use inductive system loads which leads to the lagging of current. To remedy this situation, the static capacitors are connected parallel with the electrical devices that have a low power factor (the static capacitor is indicated by “c” in the figure below). These capacitors offer leading current that neutralize the lagging current. In this manner, the power factor of the system loads will be improved.
• Low maintenance since no parts move.
• They are light thus easy to install.
• Work in any weather conditions.
• The static capacity operates for a short duration of up to 10 years.
• If the stipulated voltage increases, the capacitors are easily destroyed.
Using Synchronous motors
These devices can operate without a load. In this manner, they draw the leading current and eliminate the reactive part of the supply voltage. Consequently, the power factor will be enhanced.
• A long duration of operation of up to 25 years.
• Does not generate harmonics of maintenance.
• Faults with the motors are easy to correct.
• Maintenance involves only periodic greasing of bearings.
• Synchronous motors have no torque to start it by itself thus there is a need for an additional device for that.
Using Phase Advancer
A phase advancer is connected to the main shaft of the motor and liaises with the motor’s rotor circuit to influence the power factor. It can be an AC exciter that draws the ampere-turns that are produced by the stator windings of an induction motor. The windings usually produce 90% of the lagging current in any given device. Therefore, with the phase advancer, the power factor will be significantly improved.
• Reactive component of power is sufficiently reduced which reduces the lag in currency.
• Where the synchronous motor is not allowed, the phase advancer can be sued.
• Not viable for motors below 200 H.P.
These techniques for power factor improvement will save companies energy costs. It is therefore essential for the electrician attached to large users of power to consider the electrical devices they use and the various ways that they contribute to the lowering of the power factor. Of all the large users of energy, one of these methods of power factor improvement will come in handy.

Other scenarios when to hire a bobcat operator includes:
A new landscape design requires clearing up the area and moving earth around. Bobcat engineers came in handy at this point as they can help to get rid of small retaining walls, garden beds, digging up old turfs as well as levelling the ground to prepare for layering of a new turf. Moving mounds and dirt in a bid to develop valleys and hills are also part of landscaping that bobcat operators can achieve within minutes.
Post Hole Digging
When you want to dig holes for posts, it can take a lot of energy for one person to do it. However, when a bobcat operator uses his/her machine for digging, you will have your posts up within no time. The professional will come with a device that has a post hole digger attachment to clear up the area first if need be. From here, the expert can proceed to dig the holes which can be up to 450mm wide and 2 meters deep. The same practice also comes in handy when you want to plant large plants and small trees as the piece of equipment can dig out the holes for their root systems.
Constructing a New Pool
The construction of a new pool is another instance when to hire a bobcat operator. Men with shovels would probably take many years to dig a hole for a new pool. With an excavator, however, it may only take a couple of hours. You do not have to worry if access to your home or property is tight because a bobcat operator can use a micro or mini excavator to gain access to work on the pool.
Under House Excavations
There are times when constructing additional rooms beneath the house, is the best idea to bypass strict council restrictions, or save on yard space. Most of the times you will need to excavate the areas beneath your home to make room for the new additions.

Buying Your New Home In Today’s Market
April 21, 2017
Good for you for deciding that now is the time to buy a home. Loan terms are excellent if your credit is good and prices have never been better, and your purchase today is going to pay off big time within the next few years. Buying a house now, or investing in rental properties is without a doubt, a wise financial decision. Here are a few tips to make sure that your buying experience is smooth and flawless.
Before you put in any offer, make sure to get your financing secured. Getting yourself pre qualified will put you in a much stronger position to negotiate and will ensure that you are able to close on your purchase promptly. Pre qualified buyers are usually taken more seriously, and that is important when you come across the right price for the perfect house.
In addition, make sure that you do a bit of loan shopping before you settle on one lender. Remember that terms and conditions vary widely, and you need to compare rates and fees well before you make an offer. Once it’s time to close on your purchase, it’s too late to get a new lender if you find that rates are better elsewhere. So shop your loan first!
Once your financing is all lined up, get you paperwork to support your loan lined up too. Make sure that you have pay stubs, bank statements and tax documents all ready, because once your offer is accepted, your lender will need the most current information right away in order to process your loan quickly.
Once you start shopping for a house, don’t be afraid to look at homes that are priced slightly above what you are qualified for. Often times, homes are a bit over priced, and usually there is a little room for the sellers to come down in price, giving you a fantastic deal in the process.
Also consider homes that are listed as ‘handyman special’ or those that need a little bit of ‘TLC.’ These types of homes sometimes only need a bit of cosmetic help that you can have done for very inexpensively, and the competition is typically less because many buyers don’t want to hassle with touch ups or repairs before they move into a house.
If you are interested in investing in a rental property, go for the ones that already have renters in them. This can really keep you financially ahead of the game, because having an empty property isn’t a good way to start off your career as a land lord! If this is your first investment property, consider buying a duplex or fourplex so that you can live in one section while renting out the other portion.
In summary, buying a property in today’s market is exciting and and lucrative. Making the move to put in an offer and buy a house can start you on the right track in more ways than one. There are so many benefits that we didn’t even get to cover in this article, and without a doubt, you’ll be proud of your purchase for years to come!
