Abstract
A protection element for a meshed energy supply network of a means of transport, in particular of an aircraft, a meshed energy supply network having such protection elements, a method for protecting such a meshed energy supply network and a computer program for executing the method. The protection element comprises a control unit, which is formed to deduce a trigger time value from a detected fault impedance value of a network error that has occurred in the energy supply network and to adapt the trigger time value in the event of a subsequent change in the fault impedance value of the network error, and a separation unit for interrupting a connection between the protection element and the network error depending on the trigger time value.
