Closing surge overvoltage

In extra-high-voltage (EHV) and ultra-high-voltage (UHV) transmission systems, it is a common practice to control the closing surge overvoltage by means of an insertion resistor... [Pg.191]

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

Surge overvoltage 5. Switching surge Some kHz/0.1-20 ms Closing redosing... [Pg.179]

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

The figure clearly shows that there is no significant difference between the untransposed and transposed lines. The observation is the same as that made for the closing surge case. As far as the surge overvoltage or line insulation is concerned, the effect of line transposition is not significant. [Pg.207]

Reduction of surge overvoltages by an insertion resistor. I closing surge, a resistor insertion, b resistor off. a resistor insertion, residual voltage. II fault-cl earing surge, (a) Model circuit, (b) Calculated results. [Pg.218]
