What is Power Quality: Key Concepts and Issues about?

Power quality issues can be detected through symptoms like equipment misoperating at certain times or locations. Harmonics are distortions in the AC waveform caused by loads using power at different frequencies than 50-60Hz. There are various power quality issues including disturbances, transients, harmonics and interference. Voltage sags are brief decreases in voltage between 0.1-0.9 pu while swells are brief increases between 1.1-1.8 pu, both lasting 0.5 cycles to 1 minute. Causes of sags include faults a
