Time-voltage
sectionalizers

TVS time - voltage sectionalizer (Autoself TM) is a control system, including the control cabinet and a disconnector or a load break switch. It can be connected to the most existing switch elements in the network. The Autoself has the same purpose as a recloser but utilizes a much simplier sectionalizing algorithm. The product's reliability has been proven for more than 30 years of operation in electrical distribution networks.
