“…The computation results are in good agreement with the results obtained by analytical relation suggested in [10]. In [11], the permissible MTBF of 25 years is adopted for trans-mission-line arresters. If this criterion is adopted, then 2.5 kJ/kV of the rated voltage is the proposed surge arrester energy absorption capability for the system with tower footing impedances of 20 for all three analyzed system voltages.…”

Considering the lightning strikes, failure probability of arresters due to the highly nonlinear voltage stresses and current characteristics (v-i) of the arresters is not obvious. It means that the evaluation of failure probability and the energy capacity can be a difficult and long task. This paper presents an artificial neural network (ANN) based approach to estimate directly the failure probability of an arrester and then indirectly select the proper energy capacity to fulfill the adopted failure rate. The application of ANN is applied to a group of arresters and the results of the ANN test coincide with the analytical ones.

“…The intended number of arresters to be installed along the line was around 100, which meant that approximately 12 km of the line would be protected by LSA. To estimate the risk for the arresters to be overloaded the MTBS (Mean Time Between Surge) for the line arresters could be calculated for lightning surges of different probability of occurrence from the equation [5,6]:…”

Necessary information for making decisions regarding installation of LSA in a double circuit 400 kV line running between substation Vyborgskaya in Russia and substations Yullikyalya and Kyumi in Finland are discussed. Lightning discharge energy requirements for LSA have been calculated and the risk for single- and double-circuit lightning related faults with and without arresters has been estimated as a function of tower footing resistance. The decisions regarding ultimate number and location of arresters along the line are described and the type and technical data of the arresters selected are given. Furthermore the measuring system used to monitor lightning surges through the arresters is presented as well as the experience from the installation and the 3 years of service.

“…Studies of energy discharge typically require the Electromagnetic Transients Program (EMTP or ATP), or an equivalent program. These calculations often produce discharge duties in excess of published rating, at least for a significant portion of strokes to the line [3][4][5][6]. Another potential cause of distribution arrester failures should also be considered, namely, "backflow" currents from lightning strokes to customer facilities [7].…”

Surge arresters could practically eliminate lightning flashovers on distribution lines, if they are properly deployed in large enough numbers, and if they could survive the current and energy discharge duties imposed by high-magnitude lightning strokes. The discharge duty depends on complex interactions between the arrester locations, grounding, shielding from nearby objects, and the local lightning environment. But many factors of traditional concern with distribution arrester application, such as the lead length, surge front time, and protective margin, play little or no role in the discharge duty. Probabilistic methods determine the expected arrester failure rate. This should be much lower than the original flashover rate on the line insulation, otherwise the design is not acceptable. A transient program such as EMTP/ATP provides the best tool for calculating the discharge duty, but simplified methods are also available.
