I have a turbo generator and one probe has this weird spikes, Im blaming to bad grounding or something, not scratchs on the surface since other probe is fine, anyone have seen something similar, partial discharge? 960 is 16xFL? should I be worried?

Can't say I have ever seen this before.
The fact the other probe does not have this problem leads me to believe it is the proximeter power supply/signal conditioner.
I would change that out with new one

The X and Y probe cables probably each wind up at their Proximitors that are mounted next to one another? As a diagnostic, maybe swap probe cables to the opposite Proximitor. If the condition follows the Proximitor... then there’s your problem.
