Measurement methods and test procedures for assesing accuracy of instruments transformers for power quality measurements

Project name in Czech
Measurement methods and test procedures for assesing accuracy of instruments transformers for power quality measurements
Annotation in Czech
The overall goal of the project is the development of the metrological framework to enable the traceable calibration of ITs to be employed for PQ measurements in electricity grids, which can be used by IEC TC 38 Instrument transformers as a basis for the future standardisation about the use of ITs for PQ from IEC TC 38. The specific objectives of the project are: 1. To define accuracy and uncertainty limits of ITs in PQ measurements, by proposing and experimentally verifying specific performance indices for the single PQ parameters and by defining a new “PQ Accuracy Class” for ITs, which would be the extension of the concept of classical “accuracy class”. 2. To establish suitable reference measuring systems for ITs and methods for the evaluation of the relevant uncertainty contribution of ITs to PQ indices.
