Protecting ADC inputs
... Over drive of ADC inputs generally occurs when the rails of the driving amplifier are significantly greater than the max input range of the ADC e.g. amplifier runs from +/-15V and ADC input is 0-5V. This is particularly common in industrial designs where high voltage rails are used to accept +/-10V ...

Stray voltage
Stray voltage is the occurrence of electrical potential between two objects that ideally should not have any voltage difference between them. Small voltages often exist between two grounded objects in separate locations, due to normal current flow in the power system. Large voltages can appear on the enclosures of electrical equipment due to a fault in the electrical power system, such as a failure of insulation.
