In a word

This novel system protects workers by locking doors to sub-station cubicles housing live and exposed parts.

The project

After a contract worker was killed while working on a sub-station breaker, Enedis developed a locking system to prevent access to live equipment.

In order to gain access to this switchgear, workers must now perform a number of safety checks to ensure that the current has been cut off.

Once these checks have been performed, the worker can retrieve a key to open the breaker door.

Introduced in 2019, the system – developed by a field technician – uses an ingenious mechanism which is easy to use and inexpensive, meaning that it can be widely rolled-out. In concrete terms, it comprising a locking system which is stuck to the doors of cubicles housing live equipment.

The system has already been installed on all of Enedis’ high voltage (HTA) cubicle doors and will soon be installed on those of SEI and of local distribution companies. The system costs approximately 150€ and has obviated the need to replace breakers, thereby saving the Group 800 million Euros.

Why is this a game changer ?

A number of serious accidents avoided every year
Installed on 22 000 breakers
800 million Euros saved
About 5000 jobs of this type per year within Enedis’ scope of work
