INHE’s Automatic Sectionalizer adopts SF6 dielectric insulation technology. It works together with recloser to further improve feeder reliability. It can be used in the main line of distribution network, branch line or at user boundary. It detects fault and automatically isolates faulty sections of a network in conjunction with recloser operation. It also senses current and voltage to count the number of recloser trip operations. When the preprogrammed number of recloser operations is reached, the sectionalizer opens during the recloser dead time to isolate the downstream fault.
INHE’s Automatic Sectionalizer can be used on overhead distribution lines for all voltage classes rated up to 40.5kV(12kV, 24kV, 40.5kV) at 50/60Hz power system.
