Open 18+ pages insulation design of lightning and switching overvoltages analysis in Doc format. Transient overvoltages are originated by different sources such as lightning switching and faults. 9SWITCHING OVERVOLTAGES With the increase in transmission voltages needed to fulfil the required increase in transmitted powers switching surges have become the governing factor in the design of insulation for EHV and UHV systems. 26overvoltages do not cause flashovers to the same extent as caused by lightning. Check also: insulation and insulation design of lightning and switching overvoltages This chapter is dedicated to the analysis of slow-front overvoltages caused by switching.
26insulation has to be designed to withstand primarily lightning surges. Overvoltage is the decisive factor in the design of UHV transmission lines.

Surge arresters have non-linear voltage and current characteristics allowing them to start conduction at a specified voltage level hold the voltage for the overvoltage duration and stop conduction when the voltage.
8In the insulation design of UHV AC power transmission systems it is important to know the magnitude of switching overvoltages that may occur. Transformer failures related to lightning and switching are often reported in the gas insulated substation GIS. 22Stroke Current Magnitude GFD Insulation Flashover Voltage etc. The head steepness of switching overvoltage is generally lower than that of lightning overvoltage. 15-- Accurate insulator design Flashover because of uneven wetting-- Attention to physical layout Overvoltages -- Excellent experience no flashovers Overdesign Cost of withstand for Lightning Impulse and Switching Impulse is small exception. Simple design technique and easy to apply.
