AGI and power quality

Power quality (PQ) events such as voltage sags, surges, and momentary outages can result in consequences that are as minor as a light flicker to as serious as equipment damage. The ability to monitor such PQ characteristics can be used as a powerful tool to reduce off peak system delivery losses. Additionally being able to track PQ profiles allows for more effective management of energy peaks during high demand, thereby realizing significant savings both in rate penalties and generating avoidance.


With AGI, utilities can install smart meter nodes to monitor and report PQ quantities for both current and voltage at selected customer locations. Power quality data from customer meters that are distributed throughout the feeder can help determine the location and cause of a power quality problem. Smart meters and AGI nodes can also be programmed to report detection of potential PQ problems automatically so that utilities can take preventative actions.
