The Magnetic Balancing Test is a diagnostic electrical test performed on three-phase transformers to assess the symmetry and health of the transformer core and windings. The test helps identify abnormalities such as shorted turns, core faults, or winding imbalances by comparing induced voltages in each phase under controlled excitation conditions. During the test, a single-phase low-voltage AC supply is applied to one winding (typically the HV side), and the induced voltages on the remaining phases are measured. The measured voltages are then compared to evaluate magnetic balance across all phases. Objectives of Magnetic Balancing Test To verify uniform magnetic flux distribution in transformer core. To detect inter-turn short circuits or core faults. To assess winding symmetry and magnetic health. To identify internal abnormalities without opening the transformer.
