Electrical measurement and supervision activities implies all engineering measurements activities, including Development Accompanying Assessment (DAA) to ensure the compliance of the electrical behavior according to the design requirements of the costumers and to the respective grid codes, ensuring the conformity to all relevant standards up to the certification guidelines worldwide.

Validation of single components and the whole electrical system Includes measurement campaigns and validation of single components up to the whole system of the power generating units and power plants.

Grid code compliance and specific project requirements toward relevant standards Includes the grid code compliance of the power generating units and power plants. The main groups of the electrical measurements related to the grid code compliance are listed in the table below

Our services are focused (but not limited) through the following activities:

        • Specification of the scenarios in a measurement plane, including success criteria’s
        • On-site measurements and/or assessment of measurements
        • Verification of the compliance to the success criteria’s
        • Elaborating of optimal solutions by interactions with the public grid on the grid connection points
        • Data analysis and final measurement reports in compliance to the relevant standards
