A sectionalizer is a protective device used in electrical distribution systems to isolate faulty sections of a network. When a fault occurs, it detects the overcurrent and opens the circuit to prevent damage to equipment and maintain service to unaffected areas. After a predetermined time, if the fault clears, the sectionalizer automatically resets and closes, restoring power. If the fault persists, it remains open until manually reset, ensuring safe operation of the system.

What is the Air Break Switch?
An "air break switch' is a switching device that uses air the dielectric. Air break switches can be single pole or 'gang operated', and can be operated manually (using either a handle/ratchet mechanism or an insulated 'hook stick' made either of wood or fiberglass). Air break switches are designed for switching under load, but there is often a noticeable arc associated with switching. Air break switches can be found either in substations or out on the distribution system - either pole top or in pad-mounted metal enclosures. A breaker is a switching device that operates automatically and is specifically intended to interrupt short circuit currents (in addition to ordinary load currents). Circuit breakers can be designed using air, oil, vacuum, or SF6 gas as the dielectric. Circuit breakers are only found in substations. A recloser is a lot like a circuit breaker both in function and also the choice of dielectric. Reclosers typically have less short circuit interrupting capacity than breakers, but they are designed to automatically reclose to restore the interrupted circuit. The reason for that is that most (typically, more than 80% of the faults on overhead distribution circuits are self-clearing (tree branches, small animals, etc) and can be restored if the circuit is allowed to remain de-energized for 10-15 seconds so that the ionized air in the vicinity of the fault can dissipate. Reclosers are much less expensive than breakers. A sectionalizer is a device that is applied out on a distribution circuit that is intended to determine that a fault is located downstream of the recloser; the principle of operation is that once the sectionalizer makes the determination that the problem is downstream, it can open, and then an upstream reclosing device (either a recloser or a circuit breaker) can automatically reclose to restore service to those loads that are upstream of the sectionalizer. A sectionalizer doesn't have any current interrupting capability, but instead relies on the upstream device to interrupt fault current. A disconnector is simply a device that is used to disconnect a load. It can be an air break switch, or it could be a circuit breaker. The name implies the function and is not necessarily descriptive of the device itself.
How do you write 'works' in French?
"works" as in "(road)works" is "travaux" (masc.) "works" as in "she works" (the verb) is "travaille".
