Methods for Identification of Frequency Response Characteristic of Voltage Measurement Systems

The Technical Brochure of WG A3.45 deals with the technology of voltage measurement systems, which are covered by the standard family IEC 61869. First, an overview of all voltage measurement technologies is discussed in detail for conventional voltage transformers and low-power voltage transformers for the rated frequency and based on that, the higher frequency performance is derived. The modern requirements of the grid versus the performance requirements of secondary equipment are the basis for the required performance of the voltage measurement system in the frequency domain, but also in the time domain. Assessment criteria, reasonable accuracy classes and definitions build the base for the measurement performance and also the acceptance criteria. On the other hand, depending on the type…
