How can augmented reality impact the work of a low-voltage switchgear manufacturer?

Frequent design changes, discrepancies between design and actual conditions, a large number of possible switchgear configurations, and short delivery deadlines are now everyday challenges in the work of a manufacturer. The use of digitalization in the switchgear production process significantly improves work efficiency, reduces the number of errors, and increases overall productivity. Time-consuming tasks can be supported with computer calculations, shared cloud-based files (for example, using popular BIM – Building Information Modeling – solutions), and 3D design.

Configuration tools and BIM-based design are highly useful for determining dimensions, thermal conditions, and installation requirements of switchgear. However, they do not allow for a detailed verification of the structure or the routing of main and distribution busbars. In most cases, the manufacturer must independently determine how to implement the busbar system. This process can be significantly improved by using a precise 3D model of the switchgear developed by the technology provider. Combined with virtual reality—more specifically, augmented reality—the manufacturer can display such a model directly in the workshop and accurately verify how to assemble the structure, install internal devices, and execute the busbar system.

Augmented reality in the prefabrication process – SidiroAR in action

SidiroAR is a free mobile application supporting the design, dimensioning, and production of low-voltage switchgear. The name comes from “Siemens – Switchgear Digitalization.” The application was developed and implemented by a Polish team of software engineers from the technical support department to meet the specific needs of the local market.

The main goal of SidiroAR is to assist engineers in the design and construction of low-voltage switchgear. The use of augmented reality during assembly allows for simple and precise verification of busbar routing and bending. This also applies to the installation of devices, their connection to busbars, and their depth together with mounted accessories.

The 3D model of the switchgear enables verification of the correctness of its design and execution. In practice, delays in implementing design changes are common, which can lead to collisions during installation at the final site. The use of SidiroAR allows the manufacturer to visualize the switchgear with its actual dimensions at any place and time—including at the final installation site. This approach helps to avoid collisions before production begins, thereby eliminating additional costs associated with modifications during installation.

The design process of a switchgear system intended for visualization in augmented reality begins with transferring the switchgear schematic into the Simaris Configuration software. The program enables the creation of a switchgear layout, taking into account all the necessary elements required for its design. Material properties assigned to each component minimize the risk of errors—for example, when the power loss in a panel exceeds the permissible range.

Based on appropriate documentation in the form of a technical drawing of the switchgear, a 3D model is then prepared. For this purpose, 3D modeling software (such as Autodesk Inventor) is used, making it easy to combine all switchgear components. Additionally, the software allows publishing the designed models as 3D PDFs or for online viewing, which simplifies communication between the company developing the switchgear technology and the manufacturer.

After approval of the switchgear specification and design, the model is converted into a format compatible with the SidiroAR application, assigned to an individual user account, and uploaded to an external server. The use of cloud technology enables the manufacturer to download the switchgear model directly to their mobile device via the Internet—from virtually anywhere in the world. The SidiroAR application allows the downloaded model to be easily displayed in augmented reality.

SidiroAR is a mobile application available on both Android and iOS devices. Each user has a personalized account to which 3D models intended for augmented reality visualization are assigned. This enables licensed Sivacon switchgear manufacturers cooperating with Siemens to visualize every ordered switchgear system using AR technology.
