Protection for industrial and tertiary installations

Electrical installations in industry and the service sector are subject to faults (such as short-circuits) which can jeopardize the safety of people and equipment. These faults are rapidly detected by protective devices which selectively de-energize the faulty part of the network.

It's important to properly design and build the protection system to eliminate the risk of accidents and limit damage to equipment, while maintaining continuity of service in the healthy parts of the installation.

Protection systems, which were originally exclusively electromechanical, have evolved thanks to analog and then digital electronics. They now tend to be integrated into the installation's control system.

As well as improving the speed, selectivity and operational reliability of the protection system, this integration provides...
