Abstract

A method, system, and computer program product for detecting and interrupting a ground fault in a direct current (DC) power circuit are provided in the illustrative embodiments. A first value of a first current flow over a first part of the DC power circuit is compared with a second value of a second current flow over a second part of the DC power circuit. A voltage is generated, wherein the voltage is proportional to a difference between the first and the second values. Responsive to the voltage exceeding the threshold voltage for a threshold time, a signal output is produced, the signal configured to cause a short-circuit in the first part of the DC power circuit. The first part of the DC power circuit is interrupted responsive to the short-circuit.
