ABSTRACT
Significant investments have
been made regarding the construction of a great number of high-voltage overhead
power lines of all voltage levels, and now the questions arise on where and how
to direct the investments necessary for the maintenance of overhead power
lines. To organise the process of maintenance of overhead power lines
correctly, it is necessary to have the current information on the condition of
particular components of a line. In this paper, special attention has been paid
to the real condition of overhead power lines, with the aim of making the
decision whether some of the following measures are necessary, and to what
extent: the revitalisation for a certain number of years is perceived, the
revitalisation up to five years and reconstruction of the overhead power line is
performed, its restoration is performed or nothing is done. The approach to the
perceiving of real condition of high-voltage overhead power lines is presented
on a global block diagram. With the aim of setting out the list of priorities
for revitalisation, the criteria have been defined with regards to the real
condition of particular components of an overhead power line, as well as
pursuant to the role and importance in an electric power system. The correctly
defined criteria contribute to the solving of the problem of making a single
list of priorities for the revitalisation of high-voltage overhead power lines.
In that way, the recommendations are being given to the transmission companies,
to achieve a higher reliability of an electric power system, with a minimum
number of cancellations and a maximum extension of working life of all the
components of overhead power lines. A correct maintenance of overhead power
lines brings large financial savings to the owners of transmission companies,
and that is the primary goal in a deregulated environment.
