The logging frameworks store data related to:
Power quality and compliance
Energy and demand
Trending and forecasting
When your system’s nominal parameters are programmed into the meter, power quality events such as sags, swells and transients are automatically detected, and associated voltage and current data and waveforms are logged. Meter data is stored in non-volatile memory, so data is retained even if the meter loses power. If your system nominal values fluctuate, you can configure the meter’s setpoint learning feature to learn your power system’s normal operating values, then use that information to help identify voltage sags and swells.
The meter’s logging framework also supports burst data logging for sag/swell events. When burst data logging is enabled, additional data records immediately before and immediately after the sag/swell event are captured. Energy management systems can then retrieve this information for use in applications such as power event analysis.
You can also configure the meter to email data from the logging frameworks. Download the Internal email client feature technical note at www.schneider-electric.com for instructions on how to configure your meter to email logged data.
Meter events are recorded in the meter’s onboard event log. You can also configure the meter to record events to an external SysLog (systems log) server.
