Herein relates to a three-phase power transformer 2 SCOTT digital protective ratio to obtain a differential current of the M left Scott (SCOTT) Scott transformer in order to protect the internal winding transformer for converting the power differential relay and a method of control. SCOTT Transformer Protection rate digital differential relay, Scott transformer according to the disclosure for them; A transformer unit for measuring the primary three-phase supply and secondary T, M Left power of the Scott transformer; The measured first three-phase supply and secondary T, the M analog left power-to-analog converter for digital-to-digital conversion; It includes; and a control unit for calculating a primary T, M Left current on the basis of the three-phase power first the converted and calculates a second T, M left current.
