Abstract

PURPOSE: To protect a meter transformer from the deterioration by ultraviolet rays and the formation of carbonized conducting circuit by minute electric discharge by a method wherein a case for transformer is used of which the surrounding insulating wall is made of a magnetic insulating material.
CONSTITUTION: A primary coil 1 and a secondary coil 2 are wound around a core 3, and a case 4, which is made of a magnetic insulating material, accommodates the coil 1, 2 and the core 3. A mount 7, composed of a magnetic insulating material, forms one wall of the case 4, and provided with two pouring holes 8a, 8b. A synthetic resin 9 is poured or impregnated into the case 4 through the pouring holes 8a, 8b. By this way, the meter transformer is protected from the deterioration by ultraviolet rays, the formation of carbonized conducting circuit by minute electric discharge and the intrusion of a contaminating material. Therefor the meter transformer can be used in out of doors.
