NODE
Noedra Node — substation digitalization
NODE
- Transformer digitalization — dissolved gas analysis in three tiers (1 gas / 4 gases + moisture / 8 gases + moisture with Duval and Rogers Ratio), PD monitoring with GIC tracking, OLTC and bushing monitoring (up to six leakage currents), cooling control, and digital-twin ageing analysis
- Switchgear digitalization — circuit-breaker health with 10 kHz high-frequency sampling (coil/motor currents, contact wear, i²t, travel curves), SF₆/clean-air gas density monitoring with time-to-next-alarm and leak trend detection, and PD diagnostics with neural-network pattern recognition mapped to the single-line diagram
- Substation SCADA HMI — real-time process visualization, alarm/event management, trending and analytics, historian with SQL export, automated reporting; 99.99% uptime with seamless redundancy and automatic failover
- PAC engineering & integration — full AC PAC system design to IEC 61850, migration from hardwired to process-bus/station-bus architectures, OEM-agnostic hardware supply, delivered turnkey or as partial scopes under one accountable partner
- Cybersecurity by design — IEC 62443 and NERC CIP / NIS2 compliance, encrypted communications, audit trails, multi-factor authentication, role-based access control, read-only gateways
- Universal connectivity — over 300 protocol drivers in the substation SCADA HMI, including IEC 61850, IEC 60870-5-104, DNP3, Modbus RTU/TCP, and OPC UA for new and legacy devices
