Abstract:
Power transmission network is the most critical
part of a power system due to its connectivity with generation
and distribution stations. Though it is a riskier employment
to carry out the routine inspections of the transmission lines
manually, the task of inspection is imperative to the continuous
operation of the power system. However, the new trend of
transmission line inspection is based on extracted details of
the lines by means of Remotely Operated Vehicles (ROVs)
traversing through them. This paper proposes a method being
tested by a prototype for traversing alone the transmission
conductor, inspecting the line through real time video streaming,
detecting faults and pinpointing them through Geo Tagging.
Automated transmission line inspection and fault detection is
proposed to carry out through image processing and sensory
data acquisition. Radio Frequency (RF) technology is the main
communication mechanism between the operator and the ROV.
This technology will expand the remotely operating distance of
the ROV. Furthermore, a mechanism was developed to enable
the robot to cross over from one span to another in the
transmission network which include suspension type insulators.
