Definition of Single-Phase Recloser
Single-phase reclosers are used to protect single-phase lines, protect and control overhead distribution networks , improve reliability, reduce fire risk, and enable power system control . They can also be used in three-phase circuits where the load is primarily single-phase. In the event of a permanent phase-to-phase ground fault, one phase can be locked out while maintaining power supply to the remaining two-thirds of the system.
Because single-phase reclosers are lighter than large three-phase reclosers, they are typically mounted directly on poles or substation steel structures using built-in mounting brackets, without the need for additional mounting frames.
