Note: The parameters of the AC-DC dual-purpose test transformer are the same as the above table, the rated DC voltage in the DC parameters is 1.4 times that of the AC, and the rated DC current is 0.7 times the AC current. According to the user's needs, a medium-voltage tap of 5-15kV can be extracted from the high-voltage winding for the AC withstand voltage test of the high-voltage motor. Test transformers with special specifications can also be customized.
