Reclosing overvoltage

Effect of closing resistors on maximum overvoltages, (a) Closing surge, (b) Reclosing surge residual voltages (-1, -1, 1 pu). [Pg.200]

Figure 2.25 shows the effect of a closing resistor on a statistical distribution. It is clear how the closing resistor is effective in reducing the overvoltage in both the closing and reclosing... [Pg.204]

This result is a proof of the reason why the reclosing surge overvoltage is much higher than the closing surge overvoltage. [Pg.249]

This is usually an issue for overhead lines since auto-reclose is applied to them. For cables, it is not common to apply auto-reclose. If it is applied to cables, they may experience higher overvoltages because of their higher residual voltage. System operators are required to know that they need to wait for about 10 min (maybe more to be conservative) before reenergizing a cable, though it would not be a typical operation to reenergize a cable after a failure. [Pg.284]
