Abstract
A procedure and apparatus for increasing the ease and safety of making grounding connections in electrical distribution systems having access areas including switch and fuse blades removable by hot stick operation. A grounding blade physically interchangeable with standard fuse and switch blades is provided with convenient connections for receiving a grounding cable or cables, so that either end of the blade, or both ends thereof, can be grounded, whereby to ground system components connected thereto.
Claims4
A grounding device dimensionally interchangeable with a switch blade in high voltage electrical distribution systems comprising, in combination:
- an elongated member of electrically insulating material;
- a first electrically conductive member, at one end of said elongated member, configured like the lower terminal of a switch blade;
- a second electrically conducting member, at the other end of said elongated member, configured like the upper terminal of a switch blade;
- and means carried by each of said conducting members for connecting an electrical conductor thereto.
A grounding device dimensionally interchangeable with a fuse blade in high voltage electrical distribution systems comprising, in combination:
- an elongated member of electrically insulating material;
- a first electrically conductive member at one end of said elongated member configured like the lower terminal of a fuse blade;
- a second electrically conducting member at the other end of said elongated member configured like the upper terminal of a fuse blade, and including an insulated hot stick loop;
- and means carried by each of said conducting members for connecting an electrical conductor thereto.
The method of grounding a conductor in an electrical distribution system which comprises substituting, for a removable switch blade normally connected at one end to said conductor, a grounding device dimensionally interchangeable with said switch blade and having a grounded conductor connected thereto at said one end.
The method of grounding a conductor in an electrical distribution system which comprises substituting, for a removable fuse blade normally connected at one end to said conductor, a grounding device dimensionally interchangeable with said fuse blade and having a grounded conductor connected thereto at said one end.
