Abstract

PURPOSE:To put a voltage controller or the like into transmission limit, by connecting a low voltage coil to a different power sources, and dividing a high voltage coil into two and more in series and connecting them in parallel with one terminal of the parallel connection connected to a line side and the remaining two terminals to a tap coil. CONSTITUTION:Single phase main transformers 201-206, a voltage controller 211 and a tap changer 221 are provided. A low voltage coils 1a, 1b are connected to different power sources u1, v1, w1, u2, v2, w2 and a high voltage coil is divided in series into 5a, 6b, each connected in parallel. Terminals of the parallel connection U, V, W are connected to line side while other two terminals are connected to a tap coil 7. Said tap coil 7 connects to the neutral point side via the tap changer 221 thereby composing a three-phase circuit.
