The limitation of switching overvoltage during EHV transmission line re/energization can be achieved traditionally through usage of circuit breakers equipped with pre-insertion resistors as well as the use of MOV surge arresters at both line ends and along the line. A recent and novel technique to reduce the switching transients is controlled switching. In this paper the results of comparative analysis...
The development of an electromagnetic transient model to assess potential transient switching issues on a proposed three-ended 400 kV cable circuit is described. The key features of the PSCAD-EMTDC simulation tool and the methodology of model development and testing are discussed. Typical study results and the overall conclusions drawn from these are presented. The paper demonstrates how analysis...
Electrical power transmission is dominated by overhead line systems at present. This is mainly based on more than hundred years of experience of utilities in running overhead lines. Furthermore, overhead lines have proven their operational reliability and functional assurance. In the past, cables were used in distribution networks in urban areas for the most part with the exception of direct current...
