Measure The Electricity Usage
Have you ever thought how much electricity is being used by your home appliances and other electric-power equipment at your home? You may be getting a monthly electricity bill to help you with that. But if you had to measure the electricity usage or energy used by each electric-powered items at your home, then how to go about it? Well, this is the main objective of this page. Read on.
For whatever reason or necessity you may have in mind to measure usage of electricity at your home, basically there are three ways to go about it:1. Simple watt-hour meter
Purchase a simple watt-hour meter at your local store. After plugging in the device to the watt-hour meter, plug the meter into the supply point. When the device begins to draw current, the watt-hour meter will measure the electricity usage and give a reading. You can get the reading or a given moment and over an extended period of time.2. Whole-house meter
For measuring electricity usage of the whole house, either for any give moment for the month, then you may consider an installation of a whole-house meter. Similar to the electric meter at your home, it has some extra features that help you to measure the electricity usage for a selected period of time. The reset button on the device will reset the meter reading to zero. It will keep on recording the electricity usage until you stop it. You can compare the reading with your actual figure stated in your electric bill and make sure you are not being overcharged.3. Using your own electric meter
If you don't wish spending money on buying watt-hour meter or a whole-house meter, you can still measure the electricity usage using your home electric meter. You just need to do the following:
First, decide on the device you wan to measure and turn it off. It is a good idea to turn off the air conditioner and refrigerator for they can affect the reading if they kick in while you are making the measurement. Go to your electric meter and using a stopwatch, just measure how long does it take for the disc to spin one round. Then, turn on the device you want to measure. Go back to your electric meter to measure how much time it takes to spin one round now.
Now you are ready to do some calculations. The formula for calculation is: 3.6 x Kh fator / number of seconds = kW. The Kh factor is 7.2.
