Presentation · EN — Eight-slide Siemens Energy Grid Technologies presentation (marked Unrestricted, version 1.0, February 2026) collecting the three Level-4 product one-pagers for transformer monitoring within the Noedra Node substation-digitalization suite: Asset Sensing & Monitoring — Mechanical & Thermal, Gas, and Electrical. An opening portfolio-structure slide places the three one-pagers in the DG2.0 framework ('The Mind of the Grid') under Node › Transformer, alongside the Shield, Flow, and Atlas suites. Each one-pager shares the pitch 'Hear your substation's heartbeat — with sensing, analytics, and automation', a common main-benefits block, and a common technical-information panel (sensor set, digital-twin analytics, read-only encrypted connectivity), then differentiates by discipline: cooling control and digital-twin ageing analysis (mechanical & thermal); three dissolved-gas-analysis tiers from single-gas hydrogen monitoring to 9-gas Duval/Rogers Ratio diagnostics (gas); and partial-discharge, OLTC, and bushing monitoring with GIC tracking (electrical). The deck closes with internal one-pager template and value-driver taxonomy slides.
The opening slide shows the DG2.0 portfolio structure — Level 1 'DG2.0, The Mind of the Grid' — broken into four Level-2 suites, each carrying a periodic-table-style element tag: Shield (Ns, Grid security), Flow (Nf, Line digitalization), Node (Nn, Substation digitalization), and Atlas (Na, Energy advisory).
Within the Node suite, Level 3 splits into Transformer, Switchgear, and Substation. The Transformer row — highlighted on the slide as the scope of this deck — carries three Level-4 offerings: Mechanical & thermal, Gas, and Electrical. These are exactly the three one-pagers that follow. For reference, the sibling rows read Switchgear: Mechanical & thermal / Insulation condition / Electrical, and Substation: SCADA HMI / PAC Engineering & Integration services.
| Suite (Level 2) | Tag | Focus |
|---|---|---|
| Shield | Ns | Grid security — Identify & Assess, Protect, Detect, Respond, Recover |
| Flow | Nf | Line digitalization — Overhead Line (dynamic line rating, situation awareness and weather resilience, advanced inspection) |
| Node | Nn | Substation digitalization — Transformer, Switchgear, Substation |
| Atlas | Na | Energy advisory — Grid planning & simulation, Energy transformation, Normative & regulatory compliance |
Features at a glance: Cooling control — real-time visibility of cooler status, oil flow, and thermal behaviour, supporting hot-spot temperature calculation and thermal modelling for load optimization. Ageing analysis — a digital-twin-based ageing index and relative life loss derived from winding temperature and loading history, supporting decisions on safe overload and life extension.
The slide's three value drivers are Reliability (warning and alarm notifications to ensure the operation), Operational Excellence (monitoring critical parameters, fleet-wide visualization, OEM expertise of asset health), and Flexibility (load simulations and overload prediction based on the Thermal Digital Twin).
Three dissolved-gas-analysis options ladder up in diagnostic depth, as printed on the slide. Fidelity note: this deck labels the tiers '1 gas / 5 gases / 9 gases' (counting moisture and the diagnostic measurements into the tier names), whereas the Noedra Node transformer-digitalization brochure names the same tiers '1 gas / 4 gases + moisture / 8 gases + moisture'.
The slide's three value drivers are Reliability (warning and alarm notifications to ensure the operation), Operational Excellence (monitoring critical parameters, fleet-wide visualization, OEM expertise of asset health), and Cost optimization (relative aging to minimize operation expenses).
| Tier | Description as printed |
|---|---|
| Gas analysis – 1 gas | Continuous hydrogen monitoring for early warning of incipient faults and discharge phenomena |
| Comprehensive Gas analysis – 5 gases | Comprehensive warning — monitors four key gases and moisture in transformer oil to detect evolving faults early and pinpoint their origin |
| Complete Gas analysis – 9 gases | Early diagnostics using Duval with 8 gases + measurements and Rogers Ratio for accurate fault classification and trending |
Partial discharge monitoring: PD activity in bushings is monitored alongside power factor measurements using the same bushing sensor — no extra sensors required. PD can result from insulation defects, movement of energised parts, or design flaws; while some discharges are harmless, others can lead to insulation failure and costly outages. As added value the system also tracks Geomagnetically Induced Current (GIC) events and trends, helping prevent transformer damage.
OLTC monitoring tracks tap-changer status and behaviour to anticipate maintenance and avoid switching-related failures. Bushing monitoring provides continuous assessment of bushing insulation health — capacitance, dissipation factor, leakage current — for early detection of degradation and prevention of bushing-related failures.
