220kv sf 6 leak testing

Most leak testing today is carried out using special leak detection devices like vacuum leak detectors. These can detect far lower leak rates than methods that do not use special equipment. The function of most leak detectors is to conduct testing with a special test gas, i.e. with a medium other than the one used in normal operation.

  • Vacuum Test Chambers for SF6 Leak Testing - DILO

    When testing SF 6-filled control system components, SF 6 can remain in the test object after testing. This makes the SF 6 test method an interesting alternative to the known helium leak test in the field of GIS production, as it is not necessary to recover the test gas from the test chamber after completion of the test process. Consequently, the SF 6 test method has a shorter handling time per test unit.
