Calculation of Spacer Compression for Bundle Lines under Short-Circuit

, and .
(1998)

Abstract

In a recent Institute paper I, the authors presented experimental results on spacer compression, which showed clearly, that the simplified analytical calculation method used today, the so called Manuzio formula 2, leads to severe underestimation of spacer compression and thus to faulty spacer design. In this paper, ~urther test results are presented covering today's practical range of QJundle configurations, subspan lengths, sagging tensions and shortcircuit levels for transmission lines. Based on these results, the authors present here a new calculation method for spacer compression, which builds up on well accepted IEC standards 3, 4.
