Electronic high voltage combined measuring transformer

This paper describes a concept for controlling voltage profile in distribution network with dispersed energy resources (DER). This concept is based on fast communication links between checkpoints with a help of non-conventional instrument transformer (NCIT). NCIT´s main advantage is the possibility to adapt measuring points in high voltage power networks with new conditions regarding impact of intermittent renewable resources, harmonic distortions due to switching apparatus, smart grid systems and satisfy the requirements for prompt and accurate measurements in wider frequency range with higher dynamics. It can also provide more reliable operations. Advantage of this concept is in establishing a reliable distribution networks with proper network voltage profile.
