A French resident reports symptoms and measurements around power-line smart metering, proposes grounding and vagal mechanisms, and requests real-world assessment of wiring, ground currents and transformer emissions.
- Power lines, wiring & solar:
permanent kHz PLC (Power Line Communication)
- Proposed biological mechanisms:
Unmyelinated vagus C-fibers are selectively activated by kHz fields
- Research & federal duties:
Measurements must be done in-situ, not on test benches.
- Smart meters:
PLC Cenelec A/B smart metering
**SUMMARY FOR HHS DOCKET HHS-OASH-2026-0397 - Full report in attached PDF**
I am a French resident exposed to permanent kHz PLC (Power Line Communication) from PLC Cenelec A/B smart metering in a TT earthing system (35-90 kHz, 24/7 injection).
Current risk assessments are flawed: they evaluate the meter alone in idealized lab conditions (anechoic chamber, perfect grounding). This is irrelevant.
**The real hazard is upstream and in real degraded environments**:
- **Real-world exposure, not clean room**: In France, most rural LV networks are legacy TT with degraded neutral, unshielded overhead cables, wet soil. Injecting kHz carriers creates ground potential aberrations, high-frequency circulating currents, and makes the entire wiring a radiating antenna. The human body in the earth loop acts as parasitic antenna. Measurements must be done in-situ, not on test benches.
- **TT grounding aberration as amplifier**: My home measurements show ground current loops and body voltage at kHz. This explains chronic symptoms reported: severe asthenia, dysautonomia, non-restorative sleep.
- **Biological plausibility - Chang et al. 2022**: Unmyelinated vagus C-fibers are selectively activated by kHz fields, triggering systemic autonomic dysfunction without thermal effect. This matches my clinical picture and is ignored by thermal-only SAR limits.
- **Upstream infrastructure fragility - the hidden confusion**: Public authorities maintain confusion between the meter (low hazard by itself) and the upstream reality: cables and distribution transformers never designed for permanent kHz injection. They become fragile, prone to severe failures we observe in the field: transformer explosions, LV board fires, neutral breaks and phase shifts, premature insulation aging. Focusing only on meter emissions is a category error.
**Request**: Please evaluate (1) cumulative kHz PLC in real degraded installations, (2) TT ground current amplification, (3) vagal C-fiber kHz activation mechanism, (4) require measurement of ground currents and transformer LV emissions, not just meter box RF.
