Measurement Methods and Procedures for Assessing Accuracy of Instrument Transformers for Power Quality Measurements

Autor: M Agazar, Enrico Mohns, P. Mazza, H.E. van den Brom, M. Almutairi, Roberto Tinarelli, Gabriella Crotti, H. Cayci, Jan Meyer, Renata Styblikova, Mario Luiso

Instrument transformers (ITs) are vital components of power quality (PQ) measurement systems in electrical transmission and distribution grids. Whereas measurement methods and accuracy are well defined for PQ measurement instruments, accurate knowled
