Power quality definition

Power quality means the characteristics of electric power received by the customer, with the exception of sustained interruptions and momentary event interruptions. Characteristics of electric power that detract from its quality include waveform irregularities and voltage variations, either prolonged or transient. Power quality problems shall include, but are not limited to, disturbances such as high or low voltage, voltage spikes and transients, flickers and voltage sags, surges and short-time overvoltages, as well as harmonics and noise.

Service qualityService quality is a multidimensional quantitative description of the quality of the service supplied, it can be divided in the following main components: - Electricity Rating (or electricity available) is defined as the number units of electricity (Wh or kWh) per day required for the different end-user tiers as per their needs, regardless of the quality of the electricity during these hours.- Power Rating (or power draw) is the maximum power provided for consumption regardless of the power quality provided.- Daily Availability is the total number of hours electricity service is provided, expressed per day (daily availability) or per evening (evening availability).- Power Reliability (or interruptions) can be defined as the total unplanned and planned interruptions in comparison to the agreed service availability. l. System interruptionsTwo common measures for system interruptions are used in this document: - SAIDI is the System Average Interruption Duration Index.- SAIFI is the System Average Interruption Frequency Index. m.
