Abstract
Techniques to monitor a ground network are disclosed. In various embodiments, a test current is supplied to a ground connection from an electronic subsystem to a star point of a ground network. A voltage meter is used to read the potential difference between the ground connection and the voltage reference while the test current is being supplied to the ground connection to the star point of the ground network. The read potential difference is used to compute a computed resistance associated with the ground connection to the star point of the ground network. The computed resistance is used to determine that a detection criterion associated with the health of the ground connection to the star point of the ground network has been satisfied.
