Introduction to the Generator II

Drains are installed at various points within the generator assembly where cooling or lubricating fluids are likely to accumulate should leakage occur. These are the stator outer frame, the four hydrogen gas coolers, the high voltage bushing terminal box and the three associated terminal plates.

Pipework connects the drains to a liquid leakage detector that facilitates an analysis of any liquid leakage found. In the event of a fluid leak, alarms will be initiated in the UCR.
