TRANSIENT PROCESSES IN GROUPS OF CURRENT TRANSFORMERS FOR RELAY PROTECTION
Journal Title: International Journal of Engineering Sciences & Research Technology - Year 0, Vol 5, Issue 1
Abstract
This paper presents methods of mathematical modeling of electromagnetic processes in groups of current transformers for protection, and excluding the calculation of the electrical connection with the presentation of the main hysteresis and magnetization curve for the partial hysteresis loops. Measuring characteristics of each loads phase current transformer and their secondary circuits are specified. Results of simulation of transient process according to the proposed way causes significantly increasing of the effectiveness in solving tasks such as choosing or changing of phase current transformer, choosing of operation parameters for relay protection.
