Research into influence of compensating reactor current non-sine waving on functioning stability of protection against ground fault in oil-processing enterprise 6-10 kV networks

Authors: I.A. Kostarev, M.L. Sapunkov (Perm National Research Polytechnic University, RF, Perm)
Key words: capacity currents, compensated network, ground fault, protection, selectivity.
The authors presented the results of research and assessment of influence of ultraharmonics in the ground fault neutralizer current of on functioning stability of protection against ground faultare based on control pulsating power. It is set, that an ultraharmonics will render positive influence on selectivity of new protection. This fact is instrumental in the increase of reliability of the power supply of oil-processing enterprises.
