The reliability of high voltage electricity grids depends on the adequate testing of grid components. The aim of this pre normative research is to realise the necessary metrology required for the standardisation of high voltage testing with composite and combined wave shapes. In order to address the current lack of traceability, traceable measurement systems and calibration services will be developed for composite and combined wave shapes, and the relationship between impulse voltages with High Voltage Alternating Current (HVAC) or High Voltage Direct Current (HVDC) measurements will be determined. Input will be provided to IEC TC 42 ‘High voltage and high-current test techniques’ which revises relevant standards, in particular the IEC 60060 series.

Project duration: May 2020 – April 2023
