Abstract
A method is provided for managing a fault event in a network for distributing low-voltage or high-voltage electrical energy, which comprises at least one voltage source and a load. The method includes performing at least one step of a first procedure for detecting the existence of fault conditions in the load and performing at least one step of a second procedure for determining, on the basis of the evolution in time of the derivative of the instantaneous current in the load, the state of execution of an interruption manoeuvre started by at least one protection device adapted to interrupt locally the passage of current in the load. An electronic protection unit is also provided that is able to execute the aforesaid method.
