Power factor formula in electricity,family life in the 21st century and its changing dynamics,american pie 7 full movie free download in hindi dubbed - Test Out

Let’s say it’s friday evening, and you are with your friends at your favorite pub after really hot day. The total contents of your mug, KVA, is this summation of KW (the beer) and KVAR (the foam).
Looking at our beer mug analogy above, power factor would be the ratio of beer (KW) to beer plus foam (KVA).
The more foam you have (the higher the percentage of KVAR), the lower your ratio of KW (beer) to KVA (beer plus foam). The less foam you have (the lower the percentage of KVAR), the higher your ratio of KW (beer) to KVA (beer plus foam). It is amazing how this how often this graphic turns up when you need to discuss reactive power and explain how it can affect electricity bills. I would like to ask what is the appropriate KW rating of a generator set to used for 5 tonner aircondioning unit? Is it correct to say that the equipment itself ‘eats’ a bit of the electricity that can be generated?

Yes, that is why I was asking, but even with practice there is an amount of flip that cannot be controlled it would seem..
Limp wristing is a term used to describe a phenomenon commonly encountered by semiautomatic pistol shooters, where the shooter's grip is not firm enough to hold the frame of the pistol steady while the bolt or slide of the pistol cycles. The other alternative is to pick a firearm whose frame is heavier in relation to its slide. What you 'may' be mistaking for 'no muzzle flip' is actually getting back on target so fast you just miss the flip. The value of power factor is actually the ratio of the actual power used, and the apparent power of the system. Each time when the required power is supplied to a circuit, a part of the supplied electricity is converted in to heat while passing through the wires.

I love being outdoors, spending time with my family and helping others improve their lives by conserving energy. Power Factor Correction for reducing electric power bills of residential customers (home owners) is a scam. The meter below is measuring the power factor of a small aquarium pump, and is showing a power factor of 0.28. There are three terms you will encounter when dealing with alternating (AC) power (as opposed to DC or batteries). The second term is reactive power, and it is measured in KVAR which is short for kilo volt amp reactive. In the special case of resistive loads (like baseboard heaters or an electric stove element or old fashioned incandescent light bulb), the current and voltage are in phase. The cosine of the angle above is also equal to KW ÷ KVA so you can think of the power factor as the ratio of real power to what you measure with a volt and amp meter (apparent power).
While power factor correction is useful for many industrial customers who use large amounts of power, it is a deception when marketed to home owners (often for several hundred dollars installed) as a way to save money on their electric bill.
Adding a capacitor can increase the line voltage to dangerous levels because it interacts with the incoming power transmission lines.
Adding a capacitor to a line that has harmonic frequencies (created by some electronic equipment) on it can result in unwanted resonance and high currents. Do Power Factor Correction Devices (sometimes called Amp Reduction Units or KVAR) really save money? Power Factor Correction Devices claim to reduce residential energy bills and to prolong the productive life cycles of motors and appliances by reducing the reactive power (kVAR) that is needed from the electric utility. We have not seen any data that proves these types of products for residential use accomplish what they claim. For commercial facilities, power factor correction will rarely be cost-effective based on energy savings alone. One of the more surprising comments I have received lately was that this kind of analysis is "Rubbish" or that it doesn't address the "fact" that some acquaintance of theirs is saving money using a power factor correction device.
Despite this, people install devices like this and become convinced that any reduction in their power bill is due to the device. If your experiments lead you to conclude that you actually save significant percentages of power using one of these devices, you need to re-evaluate your controls. So, if you connect a large power factor correction unit to your PV systems inverter, you would do the following: 1) accomplish nothing in terms of resistive losses -- for that you would have had to connect the PF correction directly to things like the washing machine 2) reduce the size of the inverter required. Even if the existing PV inverter is paid for, a power factor of 1.0 should allow it to run cooler and be less likely to overload when you have too many appliances on. It might be difficult to prove if you would save money in premature inverter failures, but it would certainly be an interesting question to answer. I did one more search on power factor correction and finally found a non-technical analogy that I can use to explain this whole thing to the person trying to sell it to me:Think of a bag of potato chips.
The "imaginary" or "reactive" power is just "air" in the wires, an unavoidable part of what it takes to deliver the watts. Plugging something into a receptacle to reduce power factor is like "vacuum packing" the bag.

So connecting a capacitor in parallel with a motor helps deliver more chips per bag (watts per volt-amp) to that motor. By getting rid of the air in the bag you do not save any money since you are only being charged for the chips! BUT the power company does care about the air in the bags since the larger bags require larger "trucks" to deliver the bags.
I would respectively suggest that all electricity meters are not measuring ONLY real power.
The most popular E-Meter chips are from Analog Devices, one of the latest is the ADE7757. Filtering out-of-band AC signals, Broadband PLC modems, Narrowband PLC modems, X10 signals.
If my assumptions are correct than the correct system location for the PFC cap is directly across the meter, not at the load. Most E-meter's use an ADC (analog to digital converter) based on Audio Sigma Delta technology. For Narrow Band PLC (auto matic meter reading) the signal on the AC-line can be as high as 10Vp-p typically around 140Khz this is WAY out of band and needs to be removed before the ADC by an RC filter, many cheaper systems failed to use such a filter.
Most of the problems I have mentioned would be significantly reduced by a nice big cap right across the E-meter, hence my assumption that this is in reality what the PFC caps are doing. I have removed comments I had earlier from promoters of these scams because it became apparent that their arguments were adding nothing to the discussion and making this article more tedious to read.

Can someone who has physical access to a Formula motherboard please advise whether my understanding of the above issues is correct? It is very close to an ATX form factor, so I think it will fit your case but you should take a tape measure and make certain (if you've already the case).
EDIT: If you case has ONLY JUST ENOUGH space for the board, then it might make cabling damn near impossible. FYI, there are some embedded links in my first post, but they don't show up very well in the forum's color scheme. The right-angled SATA connectors will probably be the biggest challenge, but again, that should be manageable. We have some very common example from the real life you will understand for sure, but first let’s start with some introduction of power factor. It is the power that magnetic equipment (transformer, motor, relay etc.) needs to produce the magnetizing flux.
In reality, when we calculate KVA, we must determine the “vectorial summation” of KVAR and KW. Therefore, we must go one step further and look at the angle between these vectors.

As other posters have said, by and large a lot of folks, me included just go down to wally world and buy a 100 or 250 round value pack and head out to the range. Sometimes it will be as simple as the position of your hands along the gun and you will see a great improvement. The apparent power is actually the value produced by the multiplication of the current voltage and the rate or current flow in the circuit. One is for more commonly used in domestic settings (residential) and other one is for commercial use (businesses, factories, large motors) .

Others to look out for are KVAR Energy Saving Systems, KVAR EC, KVAR Energy Controller KEC PU1200, Nevvus Powerguard, Power-Save 1200, Power Saver HOME, Kilowatt Nanny, PowerwoRx-e3, Power Saver Enersonic and SurgeXpro. Devices with coils or capacitors (like pumps, fans and florescent light bulb ballasts) have power factors less than one. If you hook up two multimeters to measure current and voltage and then multiply the readings together, you get apparent power in volt amps, or VA. Since your motors cycle on and off and you don't use the air conditioner in the winter, there is no way to get it sized properly unless you have something to monitor the line and switch it on and off capacity (capacitors) as necessary. You can hire an engineer to do a power study, look at issues like harmonic distortion, voltage sags, equipment location, capacity of existing wiring, potential locations for the correction equipment, determine how many units are required and the values of the capacitors, and then develop a potential solution. This statement is no longer to be found now that they have reorganized their website, however, there is an archived copy here. Power factor correction devices improve power quality but do not generally improve energy efficiency (meaning they won't reduce your energy bill). The bulk of cost savings power factor correction can offer is in the form of avoided utility charges for low power factor.
This is an area that has been well understood for more than a century and concepts like resistance, impedance and reactive current are accepted as reality -- something which you ignore at your peril. Remember that if you want to test something like this with the intention of proving that it defies our current engineering knowledge, you are going to have to use calibrated test equipment and carry out carefully controlled experiments. Since these results would be violating the laws of physics, nobody will believe them unless they can repeat them. I have left out names and e-mail addresses (unless the authors request it) so that they don't get spammed. Particularly your point about connecting the power factor correction capacitor(s) directly across the inductive motor so that they are only in the circuit when the motor is switched on. The latter is analogous to what the power company sees -- increase the power factor close to 1.0, eliminate the reactive power and save money by reducing the size and capacity of equipment.
Does a $3000 inverter run at half capacity last longer, perhaps it has internal fans that don't start up until it approaches 80% capacity etc.
I agree with your conclusions BUT I think other factors might be resulting in the savings some people claim.
The very old meters certainly tried to do this but with some newer electronic meters I'm not so sure. Notice that PF error is quoted as a spec for this chip but is not mentioned in earlier chips.A  However notice that Harmonic distortion is not a meter spec, nor is AC-Line Noise rejection. This suggests that any unusual Power lineA  condition that results in a reading error can only cause a meter Increment (there is NO Meter decrement function), so unlike old meters there is no way to make the meter run backwards.

The arguments are always the same, namely a) my bills are lower, why don't you want to see them b) it's NASA approved c) recommended by the governments and universities but without links d) I don't know what I am talking about e) various promotional press releases and when that doesn't work, Ad hominem attacks.

My Mission is to live life full of adventure knowing that when it's my time, the world will be a better place because I was here and I did what I could to help others too. If they set their meters to show kWh instead of amps, there would have been no change at all and it would have become the perfect demonstration of how these devices are useless for reducing power bills. NIST Team Demystifies Utility of Power Factor Correction Devices and the much more detailed technical report NIST Technical Note 1654, Regarding Electric Energy Savings, Power Factors, and Carbon Footprints: A Primer.
If two customers both use the same amount of real energy but one has a power factor of 0.5, then that customer also draws double the current.
If you were to mount it at the air conditioner and switch it on with the air conditioner plus you sized the capacitor perfectly, then there would be no reactive power on the line going back to the fuse panel. If your power factor box is too large, then it will be providing reactive power for something else, perhaps your neighbor. It makes far more sense for modern appliances to be designed so that the power factor is close to one, and in fact, this is where the industry is headed.
The study will determine if the project makes financial sense -- even for industrial customers who get a price break for good power factor, it is not always economical.
Energy savings are usually below 1% and always below 3% of load, the higher percentage occurring where motors are a large fraction of the overall load of a facility. I don't dispute that you may have seen a reduced power bill, just the "fact" that this reduction is due to the "device" and not other factors that were overlooked. Even if future understandings of particle physics were to give us new insights to old laws -- these old laws are for all practical purposes, perfect for predicting an outcome in household situations. The temperature (degree days) vary greatly from year to year, habits change (longer or shorter showers) and a host of other things will vary your monthly power bills significantly from any chosen month from one year to the next. If nobody can duplicate your results (which is extremely likely) then you must re-evaluate your experiment. Now, multiply that exercise for every inductive motor in the home -the compressor motors for the ac and the refrigerator(s), dishwasher, hot water circulating pump(s), etc.
Power companies have to use larger diameter wiring and bigger transformers to carry the reactive power, so they encourage factories with low power factors to improve it by demanding penalties.
For you, power delivery is about the batteries, cables to the inverter, inverter, charge controller etc. Unfortunately 500Hz is only the 10th harmonic so a LOT of (switched mode power supplies) SMPS especially under light load, will consume a lot of their power at the 10th harmonic of the Line frequency (60Hz in the US), this could be completely misread by a low sampling frequency ADC. If possible, I would like to fit it inside my Lancool Dragonlord PC-K60 mid-tower case (ATX form factor). If you examine that photo, and note the locations of the right-most mounting holes, you'll see that the right side of the board will probably end up covering a llittle bit of the left side of the cable management slots, so it will be a little tight, but should be manageable. The equipment actually holds the lost power in it and releases it when needed by the circuit. This is due to energy being stored and released into inductors (motor coil) or capacitors on every AC cycle (usually  50 or 60 times per second). Power company utility meters on the side of your house measure this quantity and charge you for it. This increased current requires the power company to use larger transformers, wiring and related equipment.
If the wire between your fuse panel is very long and undersized, reducing the current would result in it running cooler and having a higher voltage at the air conditioner. First, residential customers are not charged for KVA-hour usage, but by kilowatt-hour usage. Even thinking about your energy saving device causes behavior changes -- like turning off lights when you leave a room, running the water less, etc. Finally, very few people who can set up a proper experiment are going to be willing to spend their hard earned money to purchase a device and then spend time conducting an experiment to prove that their purchase was a waste of money.
For them it is the size of wire on the poles and the size of the pole transformers, fuse capacities, size of utility poles to support the weight etc.
Judging from the Formula dimensions and photographs available on the Asus website, my case appears to have just enough available width for the board to fit. I think I will still be able to run the cables behind the motherboard tray and through the cable management slots.
I am planning to classify in SSR at the next oportunity and I will have to use .357 for the Classifier. This function both reduces the heat produced by the wires and increases the power efficiency of the system.
To recover these costs, industrial customers are charged a price premium for low power factors. This means that any savings in energy demand will not directly result in lowering a residential user's utility bill. Therefore, your monthly power bill is in no way a controlled experiment, and the savings you are hoping to measure are very small compared to regular variations.
It thus becomes obvious why these devices are not even remotely cost effective for residential applications. Reviewers at the FTC will probably take the Environmental Protection Agency and Department of Energy as a trusted source even if they don't understand the technology.
Second, the only potential for real power savings would occur if the product were only put in the circuit while a reactive load (such as a motor) were running, and taken out of the circuit when the motor is not running. Comparing power bills is useful, but only verifies significant savings such as switching from electricity to natural gas, changing high flow to low flow shower heads or other major changes.
And certainly not in the way the manufacturers recommend that they be installed, that is, permanently connecting them at the main panel. This is impractical, given that there are several motors in a typical home that can come on at any time (refrigerator, air conditioner, HVAC blower, vacuum cleaner, etc.), but the unit itself is intended for permanent, unattended connection near the house breaker panel.
