Measurement methods and test procedures for assessing accuracy of Instrument Transformers for Power Quality Measurements - Final publishable report

Original language description

Extensive integration of renewable electrical energy sources into the distribution system is essential for the implementation of “green growth” strategies. However, as integration increases electrical power quality degradation is also increasing, and therefore power quality (PQ) monitoring holds greater importance. Currently, there are no standards related to the characterisation of the instrument transformers (ITs) used for PQ measurements, even though these can introduce significant errors in the PQ measurement chain. To fill this gap, this project defined specific performance indices for ITs in PQ measurements, proposed specific PQ accuracy classes for their qualifications and developed reference measurement systems and test procedures to quantify instrument transformer (IT) accuracy and uncertainty contributions in PQ measurements. Outputs and good practice guides were provided to the Technical Committee 38 of the International Electrotechnical Commission (IEC TC 38), which is responsible for standardisation in the field of AC and/or DC current and/or voltage ITs, in particular to its working group IEC TC38/WG47, which is focused on the evolution of ITs requirements for the modern market. The project outputs in terms of reference systems and simplified test procedures, as well as measured data made available on ITs, are supporting manufactures of IT and IT test systems, as well as test and calibration laboratories in extending their products/provided services to PQ measurement. Traceability and adoption of common and standardised IT test procedures will ensure both grid operators and IT manufacturers to operate in fairer market conditions.
