Thomas Lüem Partner AG relies on planning security with elec calc GRID
Design office
Thomas Lüem Partner AG is an established electrical engineering and design office in Switzerland which offers a wide range of services: from classic low-voltage systems to photovoltaics and e-mobility solutions. The company serves as a reliable partner for building owners and project stakeholders in all matters concerning electrical design.
To meet the increasing demands for reliability, transparency, and technical accuracy, Thomas Lüem Partner AG relies on elec calc GRID. The software combines real-time calculations with grid simulation and precise selectivity analyses for maximum design reliability.
A design office with a broad scope
Whether building technology, PV systems or charging infrastructure, Thomas Lüem Partner AG covers all areas of electrical design. The portfolio is complemented by fire protection planning, building automation, lighting and lightning protection concepts, as well as consulting for innovative projects. Medium-voltage systems are also planned, especially where utilities do not provide standardized solutions.
This versatility requires tools capable of modeling complex network topologies and special cases without slowing down the design process.
Why elec calc GRID ?
The decision to use elec calc GRID was based on three key strengths:
- Real-time calculations
- Broad product neutrality
- Reliable short-circuit and selectivity analyses even for networks with multiple power sources
“elec calc GRID helps us to avoid errors in system sizing and design from the early electrical design phase,“, explains project manager Werner Rüegg.
In this way, realistic statements can be made at an early stage, budgets can be adhered to and time-consuming rescheduling can be avoided.
Use in everyday project work
Currently, two to three specialists are working with the software as core competence holders. Their goal is to establish best practices to use elec calc GRID across the company in the future. This structured rollout lays the foundation for consistent standards and efficient knowledge sharing within the team.
Variant comparison made easy
The ability to map multiple layouts within the same calculation is particularly valued. It allows users to objectively compare different scenarios such as alternative feed-in points or grid routes.
This accelerates decision-making, increases transparency, and facilitates coordination with all project stakeholders.
Selectivity as proof of quality
Selectivity analysis is another key focus. With elec calc GRID, Thomas Lüem Partner AG provides reliable, traceable evidence that is crucial for operation: faults remain local, critical consumers stay supplied and operators gain greater security during audits and commissioning.
“Selectivity calculations give our customers the confidence that we design not only planning in accordance with standards, but also with operational reliability in mind.” In addition, plant manufacturers receive the correct setting values right from the start, without waiting until project completion.
Collaboration and feedback
The team rated Trace Software’s support particularly positively: “Very good: response times are fast, and catalog adjustments are implemented quickly.“
The integration of elec calc GRID into daily work is therfore advancing collaboratively and on an equal footing.
Conclusion
With elec calc GRID, Thomas Lüem Partner AG secures a clear competitive advantage: reliable, electrical design from the early project phase. This results in fewer iterations, more informed decisions and higher documentation quality, ensuring greater security throughout the entire project.
