Who we are
Engineering for electrical installations and power systems
We prepare conceptual, main and detailed designs of power and low-current electrical installations and PV power plants. We provide construction supervision and quality control of completed installations, and carry out a full range of tests on LV installations and PV power plants.
We also prepare a variety of studies (protection settings and grid impact studies) and provide measurements, consulting and other services in electrical installations and power systems.
Electrical engineering is not just the work we do; it is our hobby, our passion and our interest.
