Digital twin and electrical panels: simulate a system before it’s even built

Digital twin for electrical panels: how it works and why it can revolutionize plant design

In the broader context of industrial digitalization, applying the digital twin to electrical panels is reshaping how plants are designed, tested, and maintained. A digital twin is a dynamic, three-dimensional and functional virtual model that mirrors the real behavior of a physical system, enabling simulations, checks, and optimizations before construction.

Already widespread in aerospace and automotive, this technology is rapidly gaining ground in industrial automation, power generation, and complex infrastructure projects.

What is a digital twin: definition and applications

A digital twin is a live digital replica of a physical asset, updated in real time with field data. For electrical panels, it can represent:

• the physical structure of the panel (dimensions, layout, wiring);
• the logic functions (automation, PLC logic, power flows);
• operating data (temperature, consumption, alarms, vibration, maintenance);
• interfaces with other systems (networks, fieldbuses, supervision layers).

This virtual replica lets you test how the system behaves under different operating conditions, evaluate performance, and anticipate anomalies or inefficiencies.

Benefits of the digital twin in panel design

Integrating a digital twin from early design stages delivers multiple advantages:

• Early validation: simulate behavior before production starts;
• Error reduction: catch conflicts and incompatibilities before wiring;
• Layout optimization: improve panel ergonomics and ventilation;
• Shorter time-to-market: fewer on-site revisions and faster commissioning;
• Easier predictive maintenance: connect the twin to real sensors and SCADA.

How to build a digital twin of an electrical panel

Creating a panel digital twin typically involves several steps:

1. 3D CAD modeling: cabinet design and component placement;
2. Logic simulation: virtual PLC programming and response testing to inputs;
3. Virtual commissioning: a full digital test of the system before real startup;
4. Live data connection: integration with sensors and real-time monitoring (IoT, SCADA);
5. Continuous updates: the twin evolves together with the physical system.

Tools and platforms for electrical digital twins

There are several software platforms to create electrical digital twins:

• EPLAN Platform (Pro Panel, Electric P8, ePULSE): 3D/2D electrical design, virtual wiring, synchronized bills of materials, and support for building the digital twin; see the official EPLAN deep-dive on the Digital Twin.
• Siemens NX, TIA Portal, and SIMIT for integrated modeling and simulation;
• E3.series for electrical design with synchronized digital twin data;
• Autodesk, Dassault Systèmes for multidisciplinary 3D environments;
• Gemini Twin, PTC ThingWorx, ABB Ability for IoT-connected industrial twins.

Sices uses EPLAN as its reference platform for electrical design and for preparing the panels’ digital twin: this ensures consistency across schematics, layout, wiring, and documentation, reducing production errors and commissioning time.

The right tool depends on plant complexity and on how deeply you need the digital twin to integrate throughout the asset lifecycle.

Digital twin and predictive maintenance

One of the most promising areas is predictive maintenance for electrical panels via digital twin. By continuously monitoring parameters such as temperature, current, vibration, and activation cycles, you can:

• anticipate faults and anomalies before they occur;
• optimize maintenance planning and spare-part readiness;
• reduce unplanned downtime;
• extend the lifecycle of critical components.

Collected data is compared to the digital model to identify deviations and progressive degradation.

Real-world applications and future scenarios

Digital twins are already used to manage:

• energy control centers and electrical substations;
• critical infrastructure (rail, airports, hospitals);
• large industrial production plants;
• photovoltaic plants and wind farms;
• smart grids and intelligent storage systems.

Looking ahead, digital twins will be increasingly integrated with AI, optimization algorithms, and augmented reality—bringing electrical panels into a new, interactive digital dimension.
