Abstract

An apparatus for detecting a ground fault of an electric power system (12) of an aircraft (10), the apparatus including a first variable resistor (102) configured to be connected to the electric power system (12), a second variable resistor (104) configured to be connected to the electric power system (12), a switch (110) movable from an open position to a closed position, the switch (110) configured to connect an electrical load (20) to the first variable resistor (102) and the second variable resistor (104) in the closed position, and a controller (112) configured to detect the ground fault based on a first voltage across the first variable resistor (102) when the switch (110) is in the opened position, a second voltage across the second variable resistor (104) when the switch (110) is in the opened position, a third voltage across the first variable resistor (102) when the switch (110) is in the closed position, and a fourth voltage across the second variable resistor (104) when the switch (110) is the closed position.
