Abstract
A system for detecting an electrostatic discharge event with respect to a device to be monitored includes a current measurement device configured to measure a current flowing via a power supply connection connecting the device to be monitored with the power supply to obtain a current measurement signal representing the current or a current component. Alternatively, a current flowing through a protective earth connection connecting the device to be monitored with the protective earth is measured to obtain the measurement signal. The system includes an electrostatic discharge event detector configured to detect an electrostatic discharge event in response to a pulse of the current measurement signal. The system may optionally include data processing of current measurement signals or values.
