Electrical rooms are becoming digital assets in their own right.
Granular IoT metering at feeders, PDUs, and MCCs streams currents, voltages, temperatures, and breaker status into a historian.
Anomaly detection spots overloads, neutral heating, and chronic phase imbalance before trip events occur.
Digital twins mirror the one‑line and equipment nameplates, simulate switching states, and help plan outages without guesswork.
Cybersecurity is foundational.
Segregated networks, read‑only historian mirrors, role‑based access, and IEC 62443 hardening keep SCADA safe while allowing engineering access.
Time‑synchronization (PTP/NTP) aligns PQ recorders and protection relays for accurate event forensics.
Maintenance is shifting from periodic to predictive.
Infrared inspections through fixed windows, temperature/partial‑discharge sensors in MV switchgear, and power‑quality trend analytics feed risk scores that generate targeted work orders.
For facilities with EV fleets and fast chargers, coordinated charging avoids transformer overloads and maintains power‑quality limits.
With clear labels, updated one‑lines, and QR‑coded as‑built documentation, technicians spend less time searching and more time fixing.
The result is safer access, faster restoration, and lower lifecycle cost—plus a data trail that proves compliance during audits.
