Health Monitoring and Power Quality Analysis of Induction Motors at Tube Well Sites of WASA Lahore

The purpose of this study is to analyze the health and power quality analysis of motors installed at different blocks of Johar Town Lahore installed by Water and Sanitation Authority (WASA) Lahore. Induction motors are the most important components of industries due to their cost-effectiveness, robustness and high efficiency. However, these motors are prone to some mechanical and electrical faults with time. Most of the faults are due to mismanagement of power and load variations. Usually, health monitoring and quality analysis of induction motors is laborious work. This study was conducted by keeping in mind the most widely used standards of the International Electro-technical Commission (IEC) and the Institute of Electrical and Electronics Engineer (IEEE). To enhance the effectiveness of the electrical systems, a detailed inspection and knowledge are needed for every power system. This technique involves taking measurements from motors in different states i.e. rest, transient and steady. The comparison of the results on different parameters with the help of graphical data is presented in this study for the safe and economical use of machines. The study covers only seven motors out of 596 installed motors at tube well sites in the city of Lahore covering almost 8 million people. There is no existing system to analyze the performance, efficiency and health of these motors. This study may be helpful in quality assurance and save from critical failure that tends to disturb the water supply system. It can also beneficial of saving the cost of repair and plant's down time. It may be recommended to analyze thoroughly the remaining tube well motors for the beneficial of WASA water supply system.
