Attachment 09 - Shaw B1921 Annex Upgrade - B1921 UPS Load Reading.pdf

This document contains two recording charts displaying electrical current measurements across multiple channels over a 12-hour monitoring period from September 16-23, 2025. The recordings capture data from channels A1, A2, A3, and AN with measurements presented in root mean square (rms) values and amperes (A).

The first chart shows cursor measurements at 9/20/2025 8:10:00 AM, displaying six cursor analysis modes: Color, Cursor 1/2 cycle MIN, Cursor MIN, Cursor AVG, Cursor MAX, and Cursor 1/2 cycle MAX. Channel values range from approximately 31.6A to 368A across the four monitored channels. The second chart presents different cursor parameters measured at 9/20/2025 7:50:00 AM, including Cursor 1/2 cycle MIN (showing 0A readings), Cursor MIN, Cursor AVG, Cursor MAX, and Cursor 1/2 cycle MAX, with values ranging from 31.9A to 530A. Both charts display identical time spans (12 hours/Div) with monitoring occurring between 9:40:00 AM on 9/16/2025 and 9:30:00 AM on 9/23/2025, and include graphical waveform representations showing current fluctuations over the monitoring period with notable spikes visible in the data.
