Introduction ION8600 Sag/Swell Module Page 2 © 2008 Schneider Electric. All rights reserved. Introduction The primary application for the Sag/Swell module is voltage quality monitoring and analysis. The module monitors voltage inputs for disturbances, which are defined as one or more of the inputs straying above a high limit (swells) or below a low limit (sags or interruptions). When it detects a disturbance, the Sag/Swell module provides information about the entire disturbance; in addition, it breaks up the disturbance into discrete components, or sub disturbances , to provide for a more detailed analysis. Sag/Swell Module in the ION8600 The Sag/Swell module in the ION8600 meter has been modified to operate a blade powered meter in a similar manner as an auxiliary powered meter. It now records outage duration and voltage level when the blade powered meter turns off (i.e. a true 3 phase outage). Typically, an auxiliary powered meter records all outages as sags because the meter is still powered up when the supply voltage goes down. An outage on a blade powered meter will cause the Sag/Swell module to respond in a similar manner. N OTE The modifications described below are for the ION8600 meter only. Method of Operation The outage duration is calculated upon start up and is registered in the DistDur output register. Outage duration is calculated as the time between the start of the sag (just before the outage) and when the meter powered up again. The startup time is considered a fixed constant when calculating the outage time. The
