Air-insulated substations

For appropriately estimating the lightning impulse withstand voltage level of substations, lightning overvoltages that would be generated in 3D complex-structure substations need to be known. [Pg.385]

Figure 5.28 shows the measured and FDTD-computed voltage waveforms. FDTD-computed waveforms agree with the corresponding measured waveforms. Note that de Oliveira and Sobrinho [33] performed a similar FDTD computation for an air-insulated substation struck by lightning. [Pg.410]

Busses are typically made of aluminum or copper and are rigid bars in the substation, insulated from gi ound and other equipment through ample insulating material, typically air or sulfurhexafluoride. The arrangement of the busses in the substation may fall into a number of different categories the most common are illustrated and explained in Table 1. The appropriate selection of configuration is made by carefully balancing cost, reliability, control, and space... [Pg.428]
