The German-based company entegra developed the intelligent 3D engineering software primtech. It is the revolutionary solution for design, construction and documentation of high-voltage substations. primtech assists in each phase of the substation life cycle, from the tender phase and initial draft through to implementation planning and in Operation & Maintenance with a digital twin. Substation engineers worldwide rely on primtech 3d for its efficiency, bringing up to 15x faster results in some phases of the design process compared to conventional design practices. primtech 3d is used worldwide by Operators, Utilities, EPC, Consultants and Engineering firms - involved in the substation design process - e.g. Siemens Energy Group, Hitachi Energy Ltd. (former ABB), Schneider Electric, L&T Construction, Fichtner, TenneT, E.ON, Amprion, Hyosung. The company entegra offers the software primtech as well as primtech training and workshops.
