![]() ![]() The core logic behind the project is to monitor the current consumption at peak hours and to activate a breaker when the consumption increases beyond the limit value for that particular consumer. according to the Solar Electric Power Association, compared to a national. The proposed system is fully automated and the main components used for the implementation of the system are an intelligent embedded system with the most modern AVR controller, a power line communication system and a set of Hall Effect sensors. NREL is a national laboratory of the U.S. To avoid complete breakdown of power a new system is introduced by which power to individual consumers could be limited that helps the suppliers for controlling and distributing the generated power. But it is a fact that power generation is not up to the mark to meet all power demands which necessitates measures like power cut, load shedding etc to meet the future demand. The consumption of electric power is increasing day by day without any control. Keywords- Power Factor, Hall Effect, Microcontroller, Current Sensor, Non-linear load The system is able to effectively measure power factor of appliances consuming power between 20W and 1000W. In the proposed hardware current measurements are taken using a Hall Effect current sensor and voltage measurements are directly obtained by stepping down the input voltage and converting it to a suitably proportional voltage input to microcontroller. This paper presents a simple, cost effective and accurate power factor measurement system implemented using ATmega microcontroller and LabVIEW. Accurate power factor measurement is important in any electrical system. The electrical energy quality is an important factor technically and economically. Dorf’s Introduction to Electric Circuits, Global Edition, is designed for a one. Practical Electronics for Inventors 2/E - Paul Scherz. Most often the AC utility mains will be the source but in certain cases it could also be the output of a motor drive, inverter or other localized AC source. Dorf 2011 Modern Control Systems, 12e, is ideal for an introductory undergraduate course in control systems for engineering. Power factor gives the relationship between the input voltage and input current waveforms to an electrical load, powered by an AC source. ![]()
