230 kV Operation of a Substation Designed for 115 kV by Controlling Voltage Transients

Arresters applied at the terminals of gas Insulated substations have been used successfully for protection from switching and lightning surges. This arrester application for gas Insulated substations permits the use of lower insulation levels and therefore more economical substations. In principle,...

Summary:Arresters applied at the terminals of gas Insulated substations have been used successfully for protection from switching and lightning surges. This arrester application for gas Insulated substations permits the use of lower insulation levels and therefore more economical substations. In principle, the same technique can be applied to air Insulated substations. This paper describes the analysis of transient voltages In a substation designed for 115 kV which Is scheduled for operatlon at 230 kV. Both arrester rating and location are considered In this analysis. It is shown that complete substation protection is possible by addition of both arresters and capacitors.
