  • Resistor, method of assembling the same, and switchgear
    Patent number: 9312669
    Abstract: A resistor for suppressing magnetizing inrush current includes a container made of an insulating material and at least one resistive element housed in the container, the resistive element being connected to two bushings provided at the container, the outer surface of the container being coated with a conductive paint, and the paint being connected to the ground, thereby being able to be located between a cable and a switch, and being able to fix the outer surface thereof to a ground voltage level so that human contact safety is not impaired.
    Type: Grant
