Disruptive Strength of Transformer Oil in Strong Magnetic Field

Abstract

It is known fact that the disruptive strength of gases is effected by the strong magnetic field. We can imagine that the strong magnetic field has also some effects on the dielectric strength of liquid dielectrics.
The authors tested the disruptive strength of transformer oil using sphere and needle electrodes under the magnetic field. of about 6000 and 11 00 gauss. They found that in the case of sphere electrodes the dis'ruptive strength increased about 3% in field strength of 6000 gauss and 4% in field strength of 11000 gauss respectively.
They found, however, in the case of needle electrodes the magnetic field has no effects on the disruptive strength of tranformer oil.
