摘要
Instrument current and voltage transformers remain the basic apparatus used in measurements of energy in electrical grid. Increasing importance of distributed energy sources necessitates more precise measurements of consumed as well as generated electrical energy. Both types occur in low voltage network where the main focus is on current transformers for electronic- type electrical energy meters. These current transformers should fulfil many requirements for precise electrical energy measurements. This paper presents a modern system for measurement of various metrological features of current transformers.
