Each event can be used to triggerparameter capture, waveform capture and/or send email as well as be used to change the state ofinternal or external I/Os.TRIGGERSThe following list highlights potential triggers. Each event trigger can be automatic or manualdepending on the selection of he user. In the case of auto trigger, the limits of the next trigger arecalculated by the meter based on the historical data; in the absence of historical data default valuesare used. In manual triggering, the meter will use the programmed limits set by the user.Each trigger input can be programmed to monitor performance, capture waveform, capture param-eters and/or send e-mail. Once an event is triggered, the Reset value will be used to check andclear the condition. Every event and it’s corresponding parameters along with the date and time ofthe occurrence are logged and available for display or retrieval using a communication port.OUT OF LIMITSThe Power Xpert Meter monitors and logs Out of Limit events for the following triggers:• System Voltage Swells and Sags• Line to Line Voltage Swells and Sags• Line to Neutral Voltage Swells and Sags• AUX Line to Line Voltage Swells and Sags• Voltage Symmetric components V0, V1 and V2• Voltage Unbalance• Over Current on all current inputs• Current Symmetric Components I0, I1 and I2• Current Unbalance• Real Power (System and Individual Phase Upper and Lower Limits)• Reactive Power (System and Individual Phase Upper and Lower Limits)• Apparent Power (System and Individual Phase Upper and Lower Limits)• Apparent Power Factor (System and Individual Phase Leading and Lagging Limits)• Displacement Power Factor (System and Individual Phase Leading and Lagging Limits)• System Upper THD Voltage (for Total)• Line to Line Upper THD Voltage (for Total)• Line to Line Upper THD Current (for Total)• Line to Neutral Upper THD Voltage (for Total)• System Lower THD Voltage (for Tota)• Line to Line Lower THD Voltage (for Total)• Line to Neutral Lower THD Voltage (for Total)• System Upper Flicker Perceptibility• Line to Line Upper Flicker Perceptibility• Line to Neutral Upper Flicker PerceptibilityDEMAND OVERLOADThe Power Xpert Meter can shed load upon demand Amperes, demand Watts, demand reverseWatts, demand vars capacitive load, demand vars inductive load or demand VA. Each DemandOverload selection has a threshold as if it were a trigger threshold. The meter can only changestate on demand window boundaries. For example, with a 15-minute fixed window, the meter canonly change state every 15 minutes.ITIC CURVEInformation Technology Industry Council update of what was known as the CBEMA Curve. Thisclassifies sag and swell events according to their magnitude and duration. The Power XpertTMMeter classifies these further with a severity rating (L1, L2, L4, L8).
