ABSTRACT

A means of controlling a work machine (100 fig.1) relative to an overhead
power line (109 fig.1) has a plurality of electric field sensors (120 fig.1).
When the machine is working in the vicinity of an overhead power line the
strength of the electric field is continuously monitored to determine if the
field strength exceeds a first threshold 440 and if so the machine is
automatically stopped 450. The operator may override the system to regain
control of the machine 470 but this may be in a derated mode where the
performance of the machine is reduced 460. Should the magnitude of the sensed
electric field reach or exceed a further predetermined threshold 480, greater
than the first, then the machine is automatically stopped again 490. The
operator may not be allowed to re-enable machine movement and may require an
administrator password to reset the system.
