Also calculate how much electricity is used for home devices and other electrical equipment in your home? You can find all your household use electricity from your monthly electricity bill, but you should measure the energy used by each object to electricity at home, as do the size? No matter why you want to measure the energy used by electric-powered items in your home, there are basically three ways to measure them: Use a simple meterYou watt-hours you can use simple meter, which can be purchased from stores premises. Simply connect the device to the watt-hour meter and then connect the meter at the point of delivery. When the design of current meter watt-hour read operation. This little device will tell you how much electricity use at any time and for a longer period of time. This simple watt-hour meter is particularly useful for determining the amount of electricity use, measured in kWh for devices that do not perform consistently as a unit of window air conditioners and refrigerators. Add the entire second home meterIf you want to monitor energy consumption home at any time, or what you used so far for the month, then you might want to consider installing a meter for the entire house. Meter is similar to the counter at home, but has advanced features to measure the use of electricity in the date range selected. When you press the reset button on the meter reading is zero, there is the use of electricity until it stopped. This meter for the entire house is very useful for monitoring the monthly use of electricity, which can be used to compare the image contained in the electricity bill and make sure they are no longer charged. Third Watch meterIf electricity not want to spend money to buy a watt-hour meter or install a meter for the entire house, you can still measure the electricity used to give immediate. You only need to use your home electricity meters. Here’s how you can do: First, turn off the device you want to monitor. To accurately measure the electricity consumption of the device, turn off air conditioners and refrigerators, affect the value if it kicks in while you are doing measurements. Then go to your electric meter with a stopwatch and measure the time required for the disk to spin the circle. Then turn on the device you want to track and return to the electric meter to measure how long it takes to run a lap. While reading, you are ready to do the calculation. Search the electricity meter to find something like print “kh X X”, where “XX” is any number, usually the seventh In This number is called factor KH. The calculation formula is: 3 6 x fator kh / cap = number of seconds kWJust measurement and KH factor into the formula for the electricity usage of the device for a specified time. For example, according to the seventh factor kh It took 60 seconds for the CD of the electricity meter to run when the device is disabled. And it took 40 seconds for the disc to spin when the device is switched on. First check the device is switched off when the show you were using (3 6×7. 2) / 60 = 432 watts. With the device turned on is the use of (3, 6×7. 2) / 40 = 648 watts. Subtracting two numbers, you get 216 watts, the power consumption of the selected device for measuring power usage.
