Abstract: Provided is a semiconductor device capable of performing fault detection on a circuit executing an AD conversion operation during the AD conversion operation. The semiconductor device includes an analog to digital conversion unit that converts a second analog signal into a first digital signal, in which the second analog signal is obtained by adding a first analog signal and an offset signal with a signal band different from the first analog signal, a signal extraction unit that extracts from the first digital signal a second digital signal corresponding to the signal band of the offset signal, and a fault detection unit that detects a fault in the analog to digital conversion unit based on the second digital signal and a setting value that is set upon generating the offset signal.

Abstract: A calibrator apparatus for calibrating the performance of partial discharge measurements at electrical components, such as high voltage cables or transformators, comprises a housing (1) and an external electrode (4) to be mounted at the housing (1). A control unit (2) generates a defined charge pulse (QS) depending on a stray capacitance (CS) of the external electrode (4) against ground, which is supplied to the electrical component.
