Reclosers are predominantly located on the distribution feeder, though as the continuous and interrupting current ratings increase, they are seen in substations, where traditionally a circuit breaker would be located. Reclosers have two basic functions on the distribution system: reliability and overcurrent protection. Reclosers are frequently applied to increase reliability, mainly due to three of their benefits: reclosing capability, single phase reclosing, and automated loop capabilities.
Sectionalizers are an economical solution to sectionalizing large outdoor networks, and often used in locations where coordination with other devices is difficult. Sectionalizers are suitable for use on outdoor medium voltage overhead distribution networks, in conjunction with automatic circuit recloser protection.
New: AutoLink protection is now extended to three-phase overhead line systems
