Are there some protection circuit in front of the AD7745 to limit the input
voltage and current while not affecting the capacitance measurement.

 

the AD7745 has no over voltage protection please refer to the absolute maximum
ratings in the datasheet.
you customer needs to ensure that a high voltage cannot be connected to the
capacitive frontend
