An X-Ray technique called Computer radiography has been developed in order to inspect High Voltage switchgears.
The technique, avoiding an invasive inspection, allows service engineers to see inside the switchgears without service interruption and the need for the insulating gas SF6 to be degassed, collected and recycled.
High Voltage switchgears in electrical networks require regular inspections to avoid the risk of unexpected malfunctions and loss of electricity supply. Computer radiography helps to obtain detailed information on equipment condition before their possible failure, and for the planning of maintenance and replacement tasks.
