Abstract: For a nation its Economical development depends widely on factors such as its education, industrial growth and many other factors and one of the most important factors amongst them is Energy consumption. Currently in our country we are facing problem such as losses in production, transmission and distribution of power which causes financial damage for everyone. In our country, there is great demand for electrical energy. This electrical energy is widely used in home as well as in various types of industries. For generation, transmission and distribution of the electrical energy cost is quite high. Due to this reason it is important to use and save the electrical energy efficiently, to reduce losses, and simultaneously the generation costs to protect the environment by reducing the power consumption. One of the most effective methods of increasing the savings and efficiency is power compensation. Power consumption is an important for all area that utilizes electrical energy. In most cases, the amount of electricity consumed by electronic and electrical appliances is not readily apparent. Many electronic appliances are produced with an information tag which tells us about its power consumption, but this is typically an average or maximum, and these appliances consume less or more power than information given on tag. Such devices such as solid state TVs, washing machines, Mixer and all other home appliances which often draw power even when they are in off state. In practice if a home appliance consume more power than its rated value then consumers must pay additional charges for monthly electricity bill. Therefore is is necessary to measure and monitor power consumption in household, an industry, particular locality at any certain time constant.
