摘要: Techniques for detecting an inrush current in a power transformer are disclosed. For example, the presence of on path may be determined by receiving signal from Rogowski coil positioned transformer, corresponding to flowing path; sampling received produce samples signal; and analyzing relative at least two criteria determine whether is present. When present, operation protective relay blocked.
