Abstract

PURPOSE: To provide the subject method comprising applying a single-phase source voltage between two-phase terminals of a Y-connection of a three-phase transformer, and connecting other terminal to the neutral point of the source, thereby to make equal the voltage allotments of the excited two-phase coils.
CONSTITUTION: In testing the induction of a transformer by applying a source voltage from a single-phase power source consisting of a single-phase generator 2 between two-phase line terminals u and v at the Y-connection side of a three-phase transformer, a line terminal other than two-phase line terminals at the Y-connection side is connected to the terminal n of the single-phase generator 2. By use of an auxiliary single-phase transformer having a neutral point at the secondary side, similar connection is carried out. In this manner, the voltage allotments of the two- phase coils to be excited can be made equal.
