摘要: Inter-turn short circuit faults are among the common occurring in dry-type air-core reactor. This paper presents an online detection method of inter-turn for reactors by using search coils. Since this type fault creates shorted turns which there high induced currents that can produce intense reversed magnetic field, field distribution is no longer symmetrical. The variety from normal condition to be monitored Based on coupled method, reactor and induction voltage coils computed different conditions. proper mounted positions suggested. proposed has been verified effective easy implementation experimentation.
