I appreciate your comments a lot. They were carried out tests of compatibility among the electronic devices (included the printed circuit board) and the oil. The oil changed color, but overalls, it lost its dielectric rigidity. Now no longer it is of 50 kV/cm but 1 kV/cm. The protection that I...
I am designing an electronic load tap changer for distribution transformers, but the thyristors are incompatible with oil's transformer; its dielectric rigidity is diminished dramatically. Is there some protection for avoiding such problem?
