‘RE’ Impulse Generators operates under a control system, which charges the impulse generator by the  charging unit.

‘RE’ Impulse Generators operates under a control system, which charges the impulse generator by the  charging unit. Charging time and charging voltage can be selected. Once the selected charging voltage has been reached, a trigger pulse initiates the firing of the lowest spark-gap of the impulse generator. When all the spark-gaps fired all the stages are connected in series thus multiplying the charging voltage. The impulse voltage divider reduces he impulse voltage to a value that the measuring and recording instruments require.
