Spark gaps

25 September 2002 Circuit & System Protection

The spark gap SGP from Citel is designed to prevent earth potential differences between equipment and structures (metal pylon, pipes) that are connected to different earthing points, due to lightning currents. When its sparkover voltage is reached, the spark gap equalises the earthing potentials and avoids drainage. The SGP is completely sealed and can be used in very harsh conditions.
