\u00a0\u00a0<\/p>\n

Extensive integration of renewables in the electrical energy distribution system is essential for the implementation of the EU objective of net-zero greenhouse gas emission by 2050. However, this integration contributes to the degradation of the quality of the electrical power, as such power quality (PQ) monitoring holds greater and greater importance. Currently, there are no standards related to the characterisation of the instrument transformers (ITs) for PQ measurements, even if ITs can introduce significant errors in the PQ measurement chain.<\/p>\n

The project aims at developing of the metrological framework for the traceable calibration of ITs employed for PQ measurements in electricity grids, that which can be used as a basis for relevant future standardisation.<\/p>\n

The specific objectives of the project are:<\/p>\n

    \n
  • To define accuracy and uncertainty limits of ITs in PQ measurements.<\/li>\n
  • To establish suitable reference measuring systems for ITs and methods for the evaluation of the relevant uncertainty contribution of ITs to PQ indices.<\/li>\n
  • To establish traceable test procedures for reference setups to calibrate ITs used for PQ measurements in electricity grids by covering limits for PQ disturbances in the available standards.<\/li>\n
  • To evaluate performance of ITs in PQ measurements in presence of multiple influence factors (e.g. temperature and temperature gradients, adjacent phases, proximity effects, vibrations).<\/li>\n
  • To contribute to a revision or issues of new reports and standards of the IEC 61869 family product (e.g. 61869-1, 61869-6, etc.) by providing the IEC TC 38 with Instrument transformers data, methods, guidelines and recommendations, necessary for the calibration of ITs used in PQ measurements.<\/li>\n<\/ul>\n
