Abstract

The oil-paper transformer is widely used as the common insulating device in the electrical industry. The transformer with the reserved primary coil and the secondary coils was filled with the transformer oil by the vacuum pouring process. Its insulating property was tested by the partial discharging (PD) system and the testing results are analyzed in detail. The experiment data reveals that the insulating properties of transformer at different positions are diverse due to the specific oil-paper structure. Obviously, the outer part of the transformer shows a much higher insulating property than its inner part. This confirms the residual air or defects are mostly concentrated in the inner part and air in the outer part is easier to be degassed by a viable vacuum pouring technology.
