Accelerator main dipole magnet system magnetic field regulation depends on its transmission line characteristic properties and its power supply system regulations. In addition, the main magnet AC power transformer configuration has indirect impact on the field quality of dipole magnet. A large accelerator main magnet system consists of hundreds, even thousands, of dipole magnets. They are linked together under selected configurations to provide uniform dipole fields when powered. When all dipole magnets are linked together in a synchrotron, they become a coupled pair of very high order complex ladder networks due to magnet parasitic capacitance, leakage resistance, and conductor resistance. In this study, we present multiphase transformer effect and harmonic response analysis of AGS main magnet system.
