Power Quality
There are different definitions for power quality.
- According to Utility, power quality is reliability.
- According to load aspect, it is defined as the power supplied for satisfactory performance of all equipment i.e., all sensitive equipment.
- This depends upon the end user. According to end user point of view, it is defined as, “any power problem manifested in voltage, current, or frequency deviations thatresult in failure or misoperation of customer equipment”
- In IEEE dictionary, power quality is defined as “the concept of powering and grounding sensitive equipment in a matter that is suitable to the operation of that equipment”.
- IEC (International Electrotechnical Commission), it is defined as, “ set of parameters defining the properties of the power supply as delivered to the user in normal operating conditions in terms of continuity of supply and characteristics of voltage (magnitude, frequency, waveform). The power supply system can only control the quality of the voltage; it has no control over the currents that particular loads might draw. Therefore, the standards in thepower quality are related to maintaining the supply voltage within certain limits.
