White dust inside generator
White dust inside generator
(OP)
Hi,
We recently opened up our generator (150MW, air cooled) to inspect for oil leaks and a general look. This is the first time I have been involved in this inspection but I noticed a thin film of white dust lying on the tops of strengthening bars and other surfaces. I am pretty sure it is not just general dust or dirt getting inside the machine. The machine has been in service for just 18 months.
Has any one heard of any similar occurrences and what the problem could be?
Thanks,
Irish Al

If so, your generator requires a look by a qualified service person and may require some cleaning and/or varnishing.

My experience has been that the problem occurred on generators that had been online for longer periods than yours.
I would definitely get a service rep involved and make sure his findings are recorded.
If you have a problem not is the time to catch it.
