1. METHODOLOGY FOR SELECTION OF OHL CANDIDATES FOR REVITALIZATION
OVERHEAD LINES IMPORTANCE-DECISION MAKING BASIS FOR REVITALIZATION NESESSITY
METHODOLOGY FOR SELECTION OF OHL CANDIDATES FOR REVITALIZATION
THE MOST IMPORTANT IS:
adequate allocation of money to those OHLs:
that are in the emergency for revitalization activities,
that have the greatest impact on reliability.

2. Figure 1 -Diagram of methodology of OHL selection for revitalization

3. RELIABILITY OF LINES WHICH ARE CANDIDATES FOR REVITALIZATION
Among more lines which have equally bad state,
the first to be revitalized is
the one with the greatest importance for consumers
and power distribution company.

6. If the revitalised line have some kinds of distribution automation that can be considered by the separate reliability estimation computer programe, developed on the University of Novi Sad.

7. The advantages of the proposed methodology are:
CONCLUSION
  The advantages of the proposed methodology are:
All OHLs are analyzed in the same way. Their availability levels are numerically determined, enabling comparation of OHLs.

8. As the result of applying of the proposed revitalization methodology, one can get the modern OHL, capable for operation in the next 40 years.

9. The OHLs so revitalized have increased reliability and nominal current.
The capital expenditures are only 40-60% of those for new OHLs but the operating costs and costs of energy losses are significantly reduced.
