Abstract: The risk of personal injury to personnel working inside energized pad-mounted transformers is reduced by providing a universally sized safety shield device that fits in place during repair operations to prevent a workman's tool from contacting the transformer face. The shield device takes the form of a rigid sheet of dielectric material having sufficient insulative value to prevent arcing inside the transformer. The shield has three slots opening to an edge of the shield with the three slots being so sized and shaped to permit them to slide over the secondary bushings to locate and hold the safety shield in place during repair operations. The shield is used in association with a pair of novel insulative bushing covers.
