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 APPENDIXES
