reforms in the power sector many new Distribution Companies have started their operations. Apart from improving financial viability‚ reduction of T&D losses the distribution reforms have been identified as a key area in terms for fulfilling consumers‘ expectations in terms of service delivery in the area of Reliability and Quality of power supply. Reliability and Quality of power supply were rarely an issue till recent past and little or no attention was paid to these aspects of power supply. If consumers‘

Introduction: Generally‚ Power quality is an issue that is becoming increasingly important to electricity consumers at all levels of usage. Sensitive power electronic equipment and non-linear loads are widely used in industrial‚ commercial and domestic applications leading to distortion in voltage and current waveforms. With ongoing regulatory‚ policy and structural changes in the Indian electricity industry‚ following the Electricity Act 2003‚ the issue of power quality is poised to become a

Background AstroPower‚ Inc. (www.astropower.com)‚ the largest US-owned manufacturer of solar electric power products‚ began as a division of Astrosystems Inc.‚ founded in 1983 as an outgrowth of semiconductor research at the University of Delaware. In 1989‚ the company was incorporated in Delaware‚ and grew rapidly. In the several years up to 2001‚ Astropower was the fastest-growing major manufacturer of solar electric (photovoltaic‚ PV) cells‚ moving into the fifth position in world market share (Figure

One only needs to consider the consequences of a relatively short power outage factories close down‚ phones and computers go dead‚ traffic slows to a crawl‚ food spoils in refrigerators to accurately observe how power-dependent our society has become.

to bone up on it before adding my voice to the cacophony of opinions‚ and recommendations. Here’s what I found: The Epira (Electric Power Industry Reform Act) of 2001 mandated the Department of Energy (DOE) to establish the Wholesale Electricity Spot Market (WESM) that would “facilitate a transparent and reliable market for electricity‚ and‚ jointly with the electric power industry participants‚ formulate the detailed rules for the WESM.” This the DOE did‚ with inputs from the industry participants

electrical meter that records consumption of electric energy in intervals of an hour or less and communicates that information at least daily back to the utility for monitoring and billing purposes. Smart meters enable two-way communication between the meter and the central system. Unlike home energy monitors‚ smart meters can gather data for remote reporting. Smart Meters" usually involve real-time or near real-time sensors‚ power outage notification‚ and power quality monitoring. Project Scope‚ Objective

Electricity meters are typically calibrated in billing units‚ the most common one being the kilowatt hour. Periodic readings of electric meters establishes billing cycles and energy used during a cycle. In settings when energy savings during certain periods are desired‚ meters may measure demand‚ the maximum use of power in some interval. In some areas the electric rates are higher during
