Personal Protective Safety Grounding

Reclamation Test Van

Maintenance of power system high-voltage equipment and transmission lines requires rigorous safety procedures. Equipment deenergized for maintenance work must be grounded to ensure the electrical safety of personnel in contact with the equipment. Field testing at a 230-kilovolt transmission line with our mobile laboratory demonstrates and evaluates the electrical safety afforded to a line crew at a grounded work site.
