Abstract
A method for protecting a bipolar power distribution network supplied with power by an electric power source isolated from an electrical ground of an aircraft. The network includes a resistive protection device configured to be connected to the electrical ground and to the two phases of the network. The method includes the steps of receiving at least one voltage value on at least one of the two phases and/or at least one current value in the electrical ground, comparing the at least one voltage value with a first predetermined threshold value and/or the at least one current value with a second predetermined threshold value and controlling the protection device by changing its resistivity according to the comparison.
