Trefton Engineering provides electrical engineering, switchgear design, BIM and technical documentation services for industrial, commercial and infrastructure projects — combining practical electrical industry experience with modern engineering software and standards-based design.
Capabilities across LV and MV switchgear, electrical design, power system studies, BIM modelling, engineering documentation and design optimization — delivered as fixed-price packages with defined deliverables.
Design and engineering of LV switchboards and control panels for industrial and commercial applications, with panel arrangement, component engineering, busbar routing and manufacturing documentation.
Medium-voltage switchgear and distribution equipment, including protection, control and interlocking arrangements with complete control and wiring documentation.
Design and drafting support for switchgear manufacturers, EPC companies, contractors and industrial projects — developed in EPLAN and AutoCAD to your standards and title blocks.
Building Information Modelling for coordinated, information-rich electrical building and infrastructure projects — from design development to as-built models.
Technical selection and sizing of electrical and control components based on system requirements, IEC standards and project specifications — technically compliant, reliable and commercially practical.
Power system analysis supporting electrical system design, equipment selection and protection requirements — delivered as formal reports suitable for consultant and client submission.
Engineering designed not only for technical compliance, but for manufacturability, efficiency and cost effectiveness — without compromising quality standards.
Structured engineering documentation supporting design approval, manufacturing, inspection, testing and project close-out — consistent from design to final records.
Share your scope — a spec, a marked-up drawing, a load list or a configurator output. Whatever you have is enough to start.
Priced per panel section or per package, with a committed submission date. No hourly billing, no surprises.
First submission within one working week of clarifications for standard panels. Revisions included until your team approves.
Final files in your native formats — EPLAN project, DWG, Revit model, PDF and Excel deliverables — ready for client submittal or the shop floor.
Informed by real-world electrical contracting and project execution experience.
Organized engineering workflows, documentation practices and revision control.
Developed with applicable IEC standards and project specifications in mind.
From individual engineering requirements to ongoing project workloads.
Based in India, supporting clients and projects across international markets.
Trefton Engineering is the engineering division of an established electrical contracting group based in Mangalore, India, with roots dating back to 1979. For more than four decades, the group has built practical experience across electrical installations, project execution and the demands of real-world electrical systems.
That contracting background shapes how we engineer: drawings are not simply documents — they must translate into equipment that can be manufactured, installed, tested, commissioned and maintained.
To build a globally trusted electrical engineering company known for technical capability, practical engineering and dependable project support.
To deliver technically sound, standards-based electrical engineering solutions that help our clients design, manufacture and execute better electrical systems.
