The invention discloses a hollow coil current transformer error environmental correlation analytical method. The hollow coil current transformer error environmental correlation analytical method comprises the following steps that an original matrix is constructed in an evaluation time window according to collected data; the original matrix is expanded based on a kalman filter, and a high-dimensionrandom matrix is established; standardized processing is conducted on the high-dimension random matrix, the high-dimension random matrix is converted to a non-hermitian matrix, the row vector averagevalue of the non-hermitian matrix is 0, and the variance of the non-hermitian matrix is 1; an influence quantity correlation evaluation matrix is obtained according to the non-hermitian matrix; and ahollow coil current transformer error environmental correlation evaluation indicator is obtained according to the influence quantity correlation evaluation matrix, and correlation between hollow coilcurrent transformer errors and environmental parameters is evaluated according to the influence quantity correlation evaluation matrix and the correlation evaluation indicator. The hollow coil current transformer error environmental correlation analytical method has the advantages that relational degree of the transformer operation errors and one or more environmental parameters can be obtained in real time, and the error state stability during the transformer operation is advantageously controlled and evaluated.
