Presentation · EN — Eight-slide Siemens Energy Grid Technologies one-pager deck (Version 1.0, 2026-Feb, marked Unrestricted) presenting the switchgear arm of the Noedra Node suite for substation digitalization under the tagline 'Listening to the Grid's Heartbeat'. A DG2.0 portfolio-structure slide places Switchgear/Asset Sensing & Monitoring as a Level-3 offering of the Node suite (Nn) with three Level-4 clusters — Mechanical & Thermal, Insulation Condition, and Electrical — each of which gets its own one-pager: circuit breaker monitoring (CBM) with 10 kHz high-frequency signal sampling and prognostics such as total i²t and motor/travel curves; gas density monitoring (GDM) for SF6 and clean air with predictive alerts, leakage detection and density trend prediction; and partial discharge monitoring (PDM) with neural-network pattern recognition and root cause analysis mapped to single-line diagrams. A shared technical platform section describes integrated real-time condition monitoring for both AIS and GIS environments with standards-based SCADA connectivity (IEC 61850, DNP3, MODBUS, OPC, IEC104, REST API). The deck is an early working version: value-driver call-outs still carry template placeholders, so no per-driver claims are transcribed here.
The opening slide shows the DG2.0 ('The Mind of the Grid') portfolio structure across four levels. Within it, the Node suite (Nn, Substation digitalization) carries three Level-3 offerings — Transformer, Switchgear, and Substation — and the Switchgear row, highlighted on the slide, breaks into the three Level-4 clusters that this deck's one-pagers cover: Mechanical & thermal, Insulation condition, and Electrical.
For context, the neighbouring Node offerings on the same slide are Transformer (Mechanical & thermal, Gas, Electrical) and Substation (SCADA HMI, PAC Engineering & Integration services); sibling Noedra suites shown are Shield (Grid security), Flow (Line digitalization), and Atlas (Energy advisory).
| Level 3 (Node suite) | Level 4 clusters |
|---|---|
| Transformer | Mechanical & thermal; Gas; Electrical |
| Switchgear (this deck) | Mechanical & thermal; Insulation condition; Electrical |
| Substation | SCADA HMI; PAC Engineering & Integration services |
Each one-pager opens with the same framing under the subline 'Hear your substation's heartbeat — with sensing, analytics, and automation': switchgear is the backbone of safe and reliable grid operation — but ageing assets, rising load demands, and the complexity of renewable integration make traditional maintenance strategies no longer enough. Failures in circuit breakers, insulation, or gas systems can lead to costly outages and safety risks.
The Nn Substation Digitalisation Suite keeps breakers, insulation, and gas systems healthy and predictable — detecting anomalies early, reducing forced outages, and streamlining maintenance for AIS and GIS environments. With real-time monitoring, advanced diagnostics, and predictive analytics, operators gain the insight needed to act before issues escalate.
The Mechanical & Thermal one-pager features circuit breaker monitoring: the system provides alarm and notification management, high-frequency signal sampling at 10 kHz with HMI visualisation, and monitoring of coil and motor currents. It includes advanced signal processing with failure mode descriptions, recommended actions, and prognostics such as total i²t, fault currents, operation counts, and motor/travel curves.
The slide illustrates the offering with a monitored 8DN8 145 kV gas-insulated switchgear bay connected to a compact CBM cabinet (11.8 x 15.7 in / 300 x 400 mm, IP20) via local connectivity over industry-standard protocols.
The Insulation Condition one-pager features gas density monitoring for SF6 and clean air: ensure environmental compliance and asset integrity with comprehensive gas density monitoring. Features include self-diagnostics, predictive alerts for upcoming alarms, and maintenance mode for SF6 operations. It includes gas leakage detection with density trend prediction and inventory management, SF6 and clean air monitoring, a comprehensive GIS system view, and mechanical lifetime tracking.
The slide shows the same monitored 8DN8 145 kV switchgear connected to a GDM cabinet (11.8 x 15.7 in / 300 x 400 mm, IP20), with connectivity either wireless via mobile communication or local via industry-standard protocols.
The Electrical one-pager features partial discharge monitoring: protect your assets with advanced partial discharge monitoring. The system provides advanced diagnostics and visualisation tools, including pattern recognition and root cause analysis using neural networks. It supports multi-channel views, alarm and notification management, and partial discharge detection mapped to single-line diagrams.
The slide pairs the monitored 8DN8 145 kV switchgear with a PDM cabinet (11.8 x 15.7 in / 300 x 400 mm, IP20) using local connectivity via industry-standard protocols. Fidelity note: this slide's 'Technical information' panel is draft placeholder text carried over from the transformer one-pager (oil level, winding, DGA and bushing sensing) and is flagged for revision on the slide itself — it is not transcribed here as switchgear capability.
Integrated, real-time condition monitoring across key switchgear assets: Siemens Energy delivers end-to-end, real-time monitoring for gas density, partial discharge, and circuit breaker performance. This integrated approach enables predictive maintenance, optimises operational efficiency, and enhances safety for both Air-Insulated (AIS) and Gas-Insulated Switchgear (GIS). With seamless data acquisition, advanced analytics, and remote access, the system ensures reliability and extends the lifecycle of high-voltage assets.
Advanced diagnostic and prognostic capabilities with expert systems: each monitoring module — Gas Density Monitoring (GDM), Partial Discharge Monitoring (PDM), and Circuit Breaker Monitoring (CBM) — incorporates sophisticated diagnostic tools: pattern recognition and root cause analysis using neural networks (especially in PDM); high-frequency signal sampling (up to 10 kHz) for detailed event capture (CBM); and predictive features such as 'Time to Next Alarm' and trend analysis for proactive maintenance planning (GDM).
Flexible, standards-based communication and seamless integration: designed for interoperability and scalability, the system supports industry-standard SCADA protocols (IEC 61850, DNP3, MODBUS, OPC, IEC104, REST API). It is compatible with Siemens and third-party equipment, suitable for both greenfield and brownfield installations, and offers web-based interfaces for multi-user access. Integration with asset management platforms ensures future-proofing and effortless deployment across diverse grid environments.

Each one-pager lists the same four main benefits: decades of operational expertise across transformers, switchgear, and substations; end-to-end solutions from sensors and analytics to integration and managed services; a compliance-led, technology-agnostic approach for multi-vendor environments; and commitment to a secure, resilient, and future-ready grid.
Document status: the deck is Version 1.0 (2026-Feb) with experience noted as 'Globally proofed'. It is an early working version — the value-driver call-outs (Reliability, Operational Excellence, and a third category) still carry template 'short explanation' placeholders on every one-pager, so no per-value-driver claims or KPIs are recorded in this entry.
