Each vacuum system is under troubles in long time operation due to air leakage from ambientair or wrong vacuum pump suction. This fact brings turbine generator into lowerelectric power production.  

‍

All these troubles are solved by our vacuum tightness audit which consists of these operations:

• Design check
• Performance measurement
• Air leakage measurement under turbine operation
• Air leakage measurement without turbine operation
• Vacuum pump suction flow measurement
• Analysis of measured data
• Repair of vacuum system
