Súvisia priečne straty a zrážky?
Main Article Content
Abstract
Abstrakt. Príspevok sa venuje problematike priečnych strát, ktoré vznikajú na vonkajších elektrických vedeniach veľmi vysokého a zvlášť vysokého napätia pri nepriaznivých poveternostných podmienkach, kedy na veľkosť uvedených strát vplývajú dva hlavné faktory: zvod a vo väčšej miere koróna. Opierajúc sa o analýzu údajov z praxe sú prezentované časové závislosti priečnych strát a intenzity zrážok v priebehu rokov 2011 a 2012.
Kľúčové slová: Prenosová sústava; priečne straty; zvod; korónový výboj
Abstract. Paper deals with the issue of transverse losses that appear on the external power lines of very high and ultra-high voltage during adverse weather conditions, when the sizes of losses are affected by two major factors: the leak and the corona. Relying on data from the practice it provides time-related transverse losses and intensity of rainfall as recorded during the years 2011 and 2012. (Are there relations between the transverse losses and the rain?)
Keywords: Transmission system; transverse losses; conductance; corona discharge
