("symptoms") five common power quality problems
1. Harmonics: Harmonics are usually caused by the operation of non-linear loads, such as inverters, computers, UPS, LED lights, etc.
2. Voltage sag / spurt / interrupt: mainly caused by external and internal causes, short-circuit faults, lightning strikes, switching operations and capacitor switching; or large equipment start-up, shutdown or impact load operation.
3. The main cause of three-phase unbalance is the uneven distribution of single-phase load in three-phase systems or large-capacity single-phase loads such as electric welders, lighting systems, railway locomotives and computer power distribution systems.
4. Transient: It may be caused by lightning, or it may be caused by switching operations such as switching capacitor banks.
5. Flicker: The main reason is that the supply voltage fluctuates. Such as electric arc furnaces, rolling mills, washing machines, etc., will cause flicker.
