Modules

accuracy_test

Per-phase accuracy test harness and test point definitions (IEC 62053-21).

channel_map

Physical ADC channel types and channel-to-phase mapping.

detector

Alarm Detector library — Rust port of the original C detector library.

energy

Active and reactive energy computation with 4-quadrant micro-joule accumulation.

events

Power quality event type definitions (dip, swell, interruption).

filters

Fixed-size moving-average filter implementation.

flicker

Flickermeter implementation constants and filters (IEC 61000-4-15).

phase

Phase angle measurement and direction classification (inductive/capacitive/in-phase).

pll

High-inertia digital PLL for grid frequency tracking and synchronization.

power

Power metrics computation (real, reactive, apparent and power factor).

print

Debug print helpers for metrology metrics.

processing

Main DSP pipeline coordinating per-cycle metric updates.
