Tap-change activity — operation counts recovered from movement of the measured voltage on the tap lattice (debounced), not a live tap position (no position channel exists in the data). Grouped by tier; click a transformer for its voltage over time, 6-month vs 2-year wear and anomaly ratio. Only 132 kV super-grid transformers carry recovered tap ops today.
