filler 21 November 2014

As part of a specialist services contract PBA manage the distribution and returns of all Sulphur Hexafluoride (SF6) gas for Transpower.  PBA provide testing and consolidation of any returned and expended SF6 cylinders.  Following an SF6 cylinder amnesty, over 200 cylinders were returned providing plenty of work for PBA’s SF6 team to get on with.  PBA have been weighing each cylinder and then testing and categorising these cylinders as new gas, reusable gas and contaminated gas.  Cylinders with an existing LAB numbers but with expired inspection dates were evacuated of all their gas and then inspected.  Those which were then assessed as being in good condition were sent to test certifiers for recertification, on return these cylinders were ready for re-use.
