The SFQ series triple frequency transformer is designed according to the Chinese standards GB311-61 and the Preventive Testing Code for Electrical Equipment to meet the requirements of the power system for high-voltage transformer double frequency induction withstand voltage test equipment. It is widely used in the AC withstand voltage test of 35-220kV series voltage transformers in the power system to assess the main and auxiliary insulation strength of the transformer, and can also conduct induction tests on the windings of motors and small transformers; It can also be used as a 150Hz power supply for short-term operation.

The SFQ series triple frequency transformer adopts a three core five column structure, and the working magnetic flux density of the iron core is selected above the saturation magnetic flux density, so that the vector sum of the fundamental potential (positive sequence vector) in the secondary winding connected in a triangular shape is 0, and the 150Hz third harmonic (zero sequence) of the same phase should be generated at both ends of the opening.
