In this research, we seek to identify the effects of a low power factor on Swaziland Electricity Company's power supply system and recommend possible solutions to the problem. The results are useful in determining how to optimally deliver power to a load at a power factor that is reasonably close to unity, thus reducing the utility's operational costs while increasing the quality of the service being supplied. The book includes the following chapters: - ABSTRACT - CHAPTER 1: INTRODUCTION - CHAPTER 2: LITERATURE REVIEW - CHAPTER 3: RESEARCH METHODOLOGY - CHAPTER 4: DATA COLLECTION - CHAPTER 5: RESULTS AND ANALYSIS OF THE SIMULATION MODEL - CHAPTER 6: BENEFITS OF POWER FACTOR CORRECTION - CHAPTER 7: FINDINGS, RECOMMENDATIONS AND CONCLUSIONS - REFERENCES
Power systems have two components of apparent power: active and reactive power. Both components are necessary for functioning of electrical systems. The active power is the average power absorbed by the resistive load. The reactive power is the measure of energy exchange between the source and reactive power of load. Energy storage devices do not dissipate or supply power, but exchange power with the rest of system. Active power is the one that is converted to other forms of energy in the load yet reactive power is only responsible for magnetizing purposes. Power factor is a ratio depicting how much of the power supplied is real. The reactive current contribute in the value of the overall ma...

A talking watch. An overcoat for two. A pair of pants for poodles. In his companion to Weird & Wacky Inventions, Jim Murphy shows kids some additional baffling and utterly silly inventions in the form of a guessing game that is both challenging and fun. What is a finger-supporting device used for? Can you really buy that talking watch? What on earth is a beard grinder? Whether it’s a device for shaping the upper lip or a life preserver for horses, this parade of unusual inventions is a real treat for trivia lovers and any curious kid with an interest in science and inventions. Ages: 9–12.

Access to modern energy is central in addressing the major global challenges of the 21st century, including poverty, climate change and famine. However large parts of the world, especially in Sub-Saharan Africa (SSA) have poor or no access to modern energy. Victoria Nalule argues that SSA countries have many common energy challenges which could be tackled with collective efforts through regional cooperation. By means of a legal and comparative analysis and a seven-step framework, the book explores the current regional mechanisms employed in Africa to address the challenge of energy poverty and access and whether they are effective in tackling the challenge of energy access, including regiona...
This 2017 Article IV Consultation highlights that the macroeconomic conditions have recently deteriorated in Swaziland. In 2016, two shocks—a prolonged drought and a sharp decline in South African Customs Union (SACU) receipts—severely hit the economy, while an expansionary fiscal policy worsened fiscal and external balances. Growth in 2016 stagnated, as agricultural productions declined, and headline inflation increased sharply, mostly owing to rising food prices. Fiscal policy remains on an expansionary course, while the monetary stance has tightened. Despite a pickup in SACU revenue, the 2017 budget envisages a continuation of large fiscal deficits, and further increase in public debt.
