POWER QUALITY IN AN ELECTRICAL SYSTEM
Electrical Power is the food for Industries, Houses, Commercial Buildings etc to drive various applications. So the Power Quality is the quality food for the given electrical process or application. Therefore power quality improves device’s ability to function properly with that electric power. "Poor Power Quality" generally mean there is sufficient deviation in the power (electrical) supply to cause equipment/process misoperation or failure. "Good Power Quality" means that the power (electrical) supply is sufficient for the equipment/process to operate satisfactorily. Equipment design is a major determinant between good and bad power quality. Definition of Power Quality: Any power problem manifested in voltage, current, or frequency deviations that results in failure or misoperation of customer equipment. Areas of Power Quality: 1. Continuity of Supply 2. Change in Voltage Level 3. Harmonics 4. Power Factor 5. Transient Voltage...
