Applying a voice recognition system for SF/sub 6/ gas insulated switchgear's inspection/maintenance services

The authors have developed a new set of portable voice recognition systems that are compact, lightweight, and have two-way communication (sending and receiving) for the purpose of inspection/maintenance services for substation equipment. The authors are using these newly developed systems for daily visual inspection, periodic inspection, and commissioning tests of substation equipment. By applying these systems with the added guidance and judgment functions, it is possible for unskilled personnel to carry out inspection/maintenance services of substation equipment. It is possible to feed the data collected at the site directly into the computer, and the trend control management can be done easily. This paper outlines the voice recognition system, the applied examples of SF6 gas insulated switchgear's (GIS) periodical inspection/maintenance, and the achieved results.
