Recloser Controls

The intelligence that enables a recloser to sense overcurrents, select timing operation, time the tripping and reclosing functions, and finally lockout is provided by the recloser control.

There are two basic types of recloser control schemes: an integral hydraulic control or an electronic control located in a separate cabinet. Hydraulic recloser control is used in most single-phase reclosers and in three-phase recloser types 6H and V6H and is built as an integral part of the recloser. Electronic recloser controls are used in most three-phase reclosers and in the single-phase recloser types VXE, NOVA STS, and NOVA¹. Compared with the hydraulic control, electronic controls are more flexible, more easily customized and programmed, and many have advanced protection, metering, and automation functionality.
