Advantages over analogues: Application reclosers PBA / TEL will: increase the reliability of electricity supply; reduce the electricity shortage; reduce the number of outages of transmission lines; reduce maintenance costs mains; improve the technical level of the operation of networks; implement modern principles of automation and management of distribution networks.

The development stage readiness: Tested experimental exploitation order

Technical and economic effect: Recloser PBA / TEL has the following features: high mechanical and switching resources; small on and off times; three times faster reclosure (O-0.1s-IN-IN-1C-1S-IN-80c-B); the ability to integrate in the remote control system (SCADA); built-in measurement; flexible detuning of the fuse; self-diagnosis; logging of operational and emergency events; resistance to electromagnetic influence on performance criteria "A"; ease of installation and operation; there is no need to conduct current, average and major overhauls during its lifetime.

Description of the development:
()
Reclosers series PBA / TEL - a new generation of switching equipment that combines advanced technology microprocessor relay protection and automation and switching technology. Recloser PBA / TEL performs the following functions: operating shift in the distribution network (local and remote reconfiguration of the network); automatic shutdown of the damaged area; automatic reclosing line (AR); automatic selection of the damaged area; automatic restoration of power to the undamaged parts of the network; Automatic collection of information about the parameters of the electric network modes. Recloser PBA / TEL can be used as a stand-alone unit for protection of outgoing power lines or with the same devices as a means of complex automation of the distribution network.
