The paper consists of the discussion of issues related to the durability of foundations of extra high voltage (EHV) power line poles and possibilities of their renovation. The research part is the diagnostics of selected foundations of the EHV line poles (400 kV) Wielopole–Noszowice. During the on-site inspection, it was found that there are chipping and small surface defects, and in some cases losses of the reinforcement cover without visible pits. Based on the degree of damage, the scope of non-structural repairs and anti-corrosive protection was determined, presenting the next stages of their implementation.

Exceeding the electric field’s limit value is not allowed in the vicinity of high-voltage power lines because of both legal and safety aspects. The design parameters of the line must be chosen so that such cases do not occur. However, analysis of several operating power lines in Europe found that the electric field strength in many cases exceeds the legally prescribed limit for the general public. To illustrate this issue and its importance, field measurement and finite element simulation results of the low-frequency electric field are presented for an active 400 kV power line. The purpose of this paper is to offer a new, economical expert system based on dynamic line rating (DLR) that utilizes the potential of real-time power line monitoring methods. The article describes the expert system’s strengths and benefits from both technical and financial points of view, highlighting DLR’s potential for application. With our proposed expert system, it is possible to increase a power line’s safety and security by ensuring that the electric field does not exceed its limit value. In this way, the authors demonstrate that DLR has other potential applications in addition to its capacity-increasing effect in the high voltage grid.
