Testing protection current transformers with CT Analyzer

Important parameters of a protection current transformer are its ratio, its excitation curve, the knee point, its winding resistance, and the burden. CT Analyzer determines all relevant current transformer data during a test duration of approximately one minute: it measures the burden of the secondary circuit, the winding resistance and the excitation curve, calculates the accuracy limiting factor for rated and actual burden, determines its ratio, amplitude and phase angle accuracy, and verifies the polarity.
