Abstract |
A capacitive device for detection of live power lines designed to be fitted on power shovels, draglines and other equipment moving along trains of mine cars is described. It detects the presence of an electric field at a distance of 14m and can stop the movement of the machine at a distance of 0.2-0.4m, stoppage occurring at a distance of 0.1-0.2m between the line and the bucket or jib. Vibration does not interfere with operation. |
