摘要：

Transformers for flash butt welding of pipes with two parallel-connected sections of the primary winding and one secondary winding are considered. The equivalent circuit for such transformers contains parallel-connected branches with resistors, coils and dependent emf sources. The coils have mutual inductive coupling. The paper proposes a method for finding the equivalent circuit parameters based on the results of measuring active powers in parallel-connected windings. The validity of the method is confirmed by the results of a numerical experiment. This method is used to find the parameters of the equivalent circuit of a powerful flash butt welding transformer.
