The paper describes a non-conventional instrument transformer (NCIT) offering the possibility of adapting the measuring points in the high-voltage power network to new states as a result of the impact of intermittent renewable energy resources, harmonic distortions evoked by switching apparatus and smart-grid systems, enabling prompt and accurate measurements in a wider frequency range at a higher dynamics, and providing more reliable operation of the power network. The features of the proposed NCIT are in using the low-power current transformers (LPCT) and in the measuring and processing electronics which are situated partially on the potential of high voltage (HV) line and partially on earth potential.
