RE, Sphere Gap is provided with Motorised arrangement to adjust the gap. The lower sphere gap shall Motorised and shall move upwards and downwards for the adjustment of gap. The upper sphere shall be hang shall be roof of the test lab with in insulator and current limiting resistance shall be provided.
‘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.
