Figure 2 provides a snapshot of the PCS100 AVC-40 event log. Input residual voltage % during the power-quality event:
Power-quality events are displayed, indicating the type of event (sag/ L1 – 78% (312 V)
dip or surge) as well as the input voltage and AVC-40 output voltage L2 – 82% (328 V)
% (corrected voltage %). The duration of the power-quality event is L3 – 86% (344 V)
also indicated. The exceptional performance of the AVC-40 can be
seen in Line 56: Output voltage % during the power-quality event:
L1 – 100% (409 V)
L2 – 99% (405 V)
L3 – 100% (409 V)
Figure 3 shows the PCS100 AVC-40 summary page, indicating the
number and range of sags/surges corrected to date.
