Abstract :
The Mead-Phoenix 500 kV AC transmission line (USA) is 243 miles long and runs parallel to the existing Mead-Liberty 345 kV line. This line is planned for 70% series and 70% shunt compensation: it also incorporates the first application of a 500 kV phase shifting transformer that enables 1300 MW transmission capacity. This paper presents the design studies that were undertaken in arriving at the equipment ratings and insulation levels that lead to the equipment specifications. The shunt reactor switching requirements utilizing metal-oxide varistors across the breaker, line switching with line connected arresters and the breaker transient recovery voltage are also dealt with in the paper
