Amoisture in the turbine steam
Bseparate lube oil lines
Ca salt water service line
Da water leak off line
AI Explanation
The correct answer is A) moisture in the turbine steam. Packing rings installed on auxiliary turbines are generally lubricated by the moisture present in the turbine steam. This moisture provides the necessary lubrication for the packing rings, which help to maintain a tight seal around the turbine shaft and prevent leakage. The other options are incorrect because separate lube oil lines, a salt water service line, or a water leak off line are not the primary means of lubricating the packing rings on auxiliary turbines.
