Development of portable 10 stages Marx Generator

High voltage equipments are often placed in open air and they are often exposed to lightning strike as well as surge voltage. They are sustaining high surge voltage during the lightning phenomena. To achieve better protection of all such power equipments and quality power supply, these voltages shou...
