    Since the 1950s, vacuum has been used as an insulating medium in switchgear. The technology has proved to be very reliable but even so, over time air will inevitably leak into vacuum interrupters and degrade the insulation. It is, therefore, essential to periodically check the integrity of the vacuum.
