TRANSFORMER ONLINE/ON-LOAD TEST

[EEENGRX]

What are some of the online/on-Load tests/PMs that can be done on a transformer? i.e when the transformer is running. i know there isn't much that can be done but a comprehensive list of some of these tests will be very helpful to better improve on what i already marked down

Thanks
