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 figure-of-merit amongst the competing distribution utilities

Construction Digital Voltmeter Raj K. Gorkhali A voltmeter finds its importance wherever voltage is to be measured. Here we present an easyto-build and accurate digital voltmeter that has been designed as a panel meter and can be used in DC power supplies panels or where it is necessary to have an accurate indication of the voltage. Circuit description The circuit uses an analogue-todigital converter ICL7107 made by INTERSIL. Fig. 1 shows the pin detail of IC L7107. This IC incorporates in

non-technological factor to shape electricity was the business- and competition-fueled "War of Currents" of the late 19th century between alternating and direct current AC and DC‚ respectively ("Electricity‚" 2006). During the initial years of electricity distribution‚ Thomas Edison ’s direct current was the standard for the United States‚ and Edison was not disposed to lose all his patent royalties. Direct current worked well for the incandescent lamps that were the principal load of the day. However

POWER System protection The purpose of any power system is to generate‚ transmit‚ and distribute electricity to the consumer in a manner that is safe‚ reliable‚ and economical; both in the short and long term. Under normal operating conditions‚ the currents‚ voltages‚ power‚ and energy associated with such systems are all matched to meet the system’s design requirements with respect to reliability‚ quality‚ safety‚ and economy. To ensure maximum returns on the large or expensive investments in the

Rectifiers Without Current Sensors Bingsen Wang‚ Member‚ IEEE‚ Giri Venkataramanan‚ Member‚ IEEE‚ and Ashish Bendre‚ Member‚ IEEE Abstract—Three-level rectifiers with reduced number of switches (such as the Vienna Rectifier) to improve the input power quality of rectifier systems have been receiving wide interest in the past years. In this paper‚ a new carrier-based pulsewidthmodulation control algorithm is proposed for such converters to eliminate the low-frequency harmonics in the line current while achieving

CHAPTER 1 Overview of Current Account Balance * Introduction: The current account is the difference between exports of goods and services and imports of goods and services. If we denote the current account balance by CA‚ we can express this definition in symbol as CA = EX – IM The current account balance is one of two major measures of the nature of a country’s foreign trade (the other being the net capital outflow. A current account surplus increases a country’s net foreign assets by the
