“…The Every Day Stress (EDS) parameter was initially proposed by CIGRÉ in 1960 [9]. The EDS, expressed as a percentage of the conductor rated tensile stress (RTS), is defined as the maximum tensile load to which the conductor can be subjected, at the temperature which will occur for the longest period of the time without any risk of damage due to Aeolian vibrations.…”

“…CIGRÉ recommends different values of EDS for overhead conductors and for conductors with dampers only, armor rods only, as well as for conductors with both dampers and armor rods. However, field observations have reported fatigue of power lines after the application of the recommended EDS values by CIGRÉ [1,7,9].…”

“…Compared to the EDS, the H/w presents several advantages, as it affects a number of parameters involved in the fatigue characteristic of conductors. One of them is that the H/w parameter takes into account the diameter of the power line conductor, which influences the energy induced by the wind and the frequency of vortex formation [7,9].…”

“…The H/w parameter has recently been suggested by CIGRÉ to better explain and describe the fatigue damage occurring on power line conductors due to the Aeolian vibration. The tenants of this parameter suggest that all overhead conductors stretched with the same value of H/w will have a similar fatigue life [9]. Although, no experimental laboratory on overhead conductors was performed to corroborate this idea.…”

The objective of this work is to evaluate the effects of mean stress on the fatigue behaviour of an All Aluminium Conductor (AAC Orchid), Aluminium Conductor Steel Reinforced (ACSR Tern), and an Aluminium Conductor Alloy Reinforced (ACAR 750 MCM). In this sense, 72 fatigue tests on overhead conductors were performed using different values of H/w parameter. Based on the experimental results, the parameters which describe the fatigue behaviour of the conductors were determined after generating theirs S-N curves. In the assessment of the mean stress effects on the fatigue life, Goodman and Gerber’s relations were fitted to evaluate the use of such models for the conductors. It was observed that the evaluation of the mean stress effect on the overhead conductor could be made by using the fatigue relations.

“…Table 3, extracted from [21]. Reference [16] presents a comparison between the tension requirements of NESC and IEC, with similar values as the ones presented here. The recommended tension limits shown in Table 3 can provide a starting point for establishing the thresholds at which a sensor application can trigger warnings and alarms when confronted with abnormal mechanical conditions in a transmission line.…”
