Overvoltage category iii

WebOvervoltage in an electric power system is a voltage: between one line conductor and earth or across a longitudinal insulation having a peak value exceeding the corresponding peak of the highest voltage of the system divided by √3 or; between phase conductors having a peak value exceeding the amplitude of the highest voltage of the system.
