General Information
GD8000 power transformer degaussing instrument is to eliminate hazards of the residual magnetism after the DC resistance test of large power transformers. It can protect power transformer from inrush current impact, also has an extremely important role in safety commissioning.
Due to the inherent hysteresis of the ferromagnetic materials, after the transformer voltage ratio, DC resistance measurement, the residual magnetism will remain in the transformer core. When the transformer put into operation, the residual magnetism will make transformer core in half saturation and generate a large number of harmonics in excitation current, which will increase the reactive power consumption of transformers and may cause malfunction of relay. Therefore, we should do the degaussing work to ensure safe running before the transformer put into operation.
