VOLTAGE IRREGULARITY REPORT — Brieske residence, Orcutt CA ==================================================================== Window: Since PG&E's monitor went up Mon Aug 17, 1:00 PM to Wed Sep 23, 11:03 AM Generated: 2026-09-23 11:03:39 PDT Coverage: 39,183 samples logged today across 87 retained detail files. Measurement method: three TP-Link EP25 metering outlets record true-RMS line voltage once per second on both 120 V legs of the split-phase service. A Tesla Wall Connector supplies the 240 V line-to-line reference and grid frequency, which is independent of the neutral. A Ting (Whisker) sensor on Leg A samples far faster than 1 Hz and retains the lowest and highest voltage it sees, so it resolves brief excursions that a 1 s RMS average necessarily flattens in both directions. Where the two disagree, the Ting figure is the closer estimate of the real extreme. What is listed: any reading below 114 V (the ANSI C84.1 Range A lower limit) and any reading above 127 V (the Range B upper limit) at 120 V nominal. Undervoltage dims and stalls equipment; sustained overvoltage damages it, so both are reported. Also recorded but not listed individually: 32 brief high readings on a 120 V branch meter, peaking at 127.4 V. These are held back for two reasons: readings between 126 V and 127 V are inside ANSI Range B, which the standard tolerates as occasional; and none of them were confirmed by the neutral-independent 240 V line-to-line reference, which never left its limits. They are reported as a count so that nothing is hidden, not because they are being claimed.
