Will there be any substantial drop in the oil level of gear box from its normal mark while it is running?
This gear box with 200 HP Drive motor for 5000 ton chiller. While it is running the level of oil comes down to its lowest in the sight glass.
Could it be considerably lower from its normal oil level mark while running?
Please help me.

Yes, it likely will come down in the oil level sight glass. You should determine if the OEM specifies the level with the machine shut down, running, or in a few instances both. The machines I have worked with have the oil level gage outside the tower and a means to add oil from a position outside the tower.
How much it varies is a function of the specific gearbox so if your next question is to ask "how much lower will it be?", don't expect a reliable answer, just "guessestimations".
By the way there is a forum on Lubrication at https://www.maintenance.org/for...ion-and-oil-analysis.
