    The test pressure for gas analysis in medium voltage switchgear is often too low. For this reason the compressor unit is needed to compress the gas to be measured so that there is sufficient pressure for the gas measuring devices connected downstream from the compressor unit. As the device is leak-tested there are no SF6 emissions.
