Maximum — Demand Electrical

+---------------------+------------------+ | Period | Peak Demand (kW) | +---------------------+------------------+ | 2026-04-01 to 07 | 142.3 | | 2026-03-25 to 31 | 138.9 | +---------------------+------------------+ | Condition | Handling | |-----------|----------| | Power loss | Persist buffer & peak to EEPROM. On restart, wait for full window before reliable demand. | | Incomplete window at startup | Use partial window average with a flag. | | Meter rollover | Detect by comparing readings; adjust delta with max meter reading. | | Communication delay | Timestamp each reading; interpolate if needed. | 9.

For kVA demand (common for utilities), measure voltage and current, then: maximum demand electrical

kVA = (kW) / Power Factor OR directly measure kVA = (V × I × sqrt(3))/1000 for 3‑phase Minimal table schema (SQLite example): | | Meter rollover | Detect by comparing
