The AES discriminates between permanent and temporary faults (faults that are spontaneously cleared without intervention and do not require opening of the line). It has been demonstrated that more than 90% of distribution network faults are self-clearing temporary faults (typically a tree branch short-circuiting one phase to ground and disappearing after the first reclosing operation). Today, these faults lead to fuse blow-up, unnecessarily opening the line and interrupting service, which causes service quality indicators to plummet. The AES is endowed with a local intelligence capable of deciding upon the nature of the fault: it only opens the line and interrupts service when, due to a permanent nature of the fault, this action is absolutely unavoidable.

The AES offers real solutions for real problems, generating true value for the users.
