••••••>Modern Technology in Transmission Lines
As part of the federal Government's policy of modernizing the electrical grids, every
transmission operator needs to asses the exact physical properties of their high voltage
transmission lines. This assessment will help in achieving operational excellence by reducing
the associated risks. Using modern technologies like LiDAR, it is possible to precisely map the
transmission assets and predict changes based on various parameters. The vegetation risk
can also be identified by using Transmission LiDAR.
According to the federal mandate, just identifying the vegetation risk will not be enough. The
utility also needs to prioritize and plan to remove the vegetation which is a risk to the
transmission lines. To ensure compliance, an audit able plan of action also needs to be
created. Doing all these is not possible by the traditional methods.
On the other hand, modern remote sensing techniques in combination with state of the art
analytics software help utilities to take the precise inventory including the accurate location of
all substations, conductor and transmission towers with their exact geographical location.
Moreover, Transmission LiDAR also helps in analyzing various on- field threats and provides
the ways to remove those.
Modern technologies like airborne LiDAR are employed for the purpose of identification and
mapping of the assets, ancillary structures and vegetation cover of a utility. But only data
collection is not enough. So business analytics software is used to transpose this data into
digital three dimensional models of the utility. This model is capable of determining line sag
under different operating variables. As a result it is the perfect tool to detect unforeseen risks
as well as realizing untapped potential of the utility.
The entire process is done in four stages. The first stage identifies the vegetation of the utility
by Transmission LiDAR. It also involves preparation of the digital models from the collected
data. The next step asses the risk by carefully analyzing the 3-D models. The measurement
and prioritize of the risk factors are also done on this stage. In the third stage scheduling of
risk removal is done. This stage also deals with executing the risk removal. The final stage
involves documenting the entire procedure and auditing it. It is also checked if the work was
done maintaining all the federal specifications.
