Our Services
Circuit Diagrams
We create certified circuit diagrams for your systems – from overview diagrams to detailed schematic diagrams. We help you meet regulatory requirements and pass building code inspections while ensuring your drawings are cleanly integrated into your revision management. Working with EPLAN Electric P8, we comply with EN 81346, EN 60617, DIN EN 61082, and IEC 61355.To circuit diagrams
Network calculation
We calculate the relevant grid parameters for your system and dimension the appropriate protective devices – laying the foundation for safe, standards-compliant operation. For one company, we helped eliminate hazards to both the facility and employees. In a subsequent fault incident, this prevented damage in the high five-figure range.To calculation
Energy Efficiency
We improve the availability of your power grids and measurably reduce your energy consumption. In the steel industry, this allowed an investment of €100,000 to pay for itself in the very first year through annual savings of €600,000.To energy efficiency
Risk assessment
We create risk assessments for your systems and activities, including the appropriate inspection intervals – allowing you to identify potential hazards early on. With our support, a client with over 80 risk assessments was able to significantly reduce effort and permanently ensure compliance during audits – without adding extra staff.To risk assessment
Short-circuit calculation
We determine the short-circuit currents in your system and evaluate the safety of your electrical equipment – documented in a standards-compliant and traceable manner.To short-circuit calculation
Selectivity calculation
Through selectivity calculations, we ensure that in the event of a fault, only the affected part of the system is shut down – not your entire operation. This protects your availability and minimizes downtime.To selectivity calculation
Distribution diagrams & distribution legends
We document the structure of your power distributors in detail – presenting circuits, fuses, cable cross-sections, and connections clearly and in compliance with standards. If required, we survey existing distributors directly on-site and transfer them into a clean, up-to-dateTo distribution diagrams
Arc flash calculation & PPE selection
We calculate the arc flash energy at your workplaces and determine the necessary personal protective equipment as well as all required protective measures – ensuring your safety when working on live systems. To PPE Selection
Risk Assessment for Machinery
We prepare risk assessments for your machinery and systems – based on the Machinery Regulation and occupational health and safety regulations.To the Risk AssessmentPlanning Process Optimization
We optimize your engineering and internal planning processes. In a mechanical engineering reference project, we were able to reduce the engineering effort for a group of systems to the point where the time spent by the responsible electrical engineer dropped to almost 0% – allowing that freed-up capacity to be channeled entirely into development work.To Process Optimization
Assessment of Existing Systems
We evaluate existing electrical installations and demonstrate how legal requirements can be met with minimal effort. For one company, this enabled a solution to be implemented for around €100,000, whereas replacement costs of €300,000 to €500,000 were originally anticipated. Our methodology is legally vetted – ensuring audit-proof documentation.To evaluation
Remediation of Building Code Inspection Deficiencies
Following building law inspections (e.g., according to SPrüfV, TPrüfVO, PrüfVO, or PVO), we support you in addressing identified deficiencies – from comparing approval documents and conducting technical negotiations with experts to finding the most cost-effective, viable solution for the remaining points. For a company with around 150 identified deficiencies, this approach reduced the number to 90 even before the first technician arrived on site.Learn morePlanning and Concept Design
We design electrical systems from the ground up – from the initial concept and dimensioning to the finalized layout documentation. Our services include ventilation systems, fire alarm systems, emergency lighting systems, and automation systems, among others. In doing so, we professionally implement identification systems such as KKS and BMK in accordance with DIN EN 81346-2.To planning
CAD Drawings
In addition to creating circuit diagrams, we produce technical drawings in AutoCAD – including installation plans, wiring diagrams, and layout drawings for your systems. In one reference project, we helped a client set up and verify their complete documentation, enabling them to move into their new building without further delay after the relocation had previously stalled.To CAD Drawings
