7sd80 High Efficiency Electrical Digital Cable Differential Protection Relay

We Export, Distribute, Trade, and Supply 7SD80 Cable Differential Relays in Navi Mumbai, Maharashtra, India. The line differential protection SIPROTEC 7SD80 has been conceived for selective line protection of power cables and overhead lines up to 24km for all kinds of Starpoint configurations. The implemented phase comparison algorithm is a fast and stable method for line protection in industry and distribution grids. The protection interface communication is carried out directly without external equipment over copper wires, optical fibers, or both in redundancy. The wide scope of nondirectional and directional functions can be applied miscellaneously as emergency functions as well as backup functions. For instance, the 7SD80 enables simplified and cost-saving concepts for meshed grids and busbar protection using reverse interlocking. Fast and selective tripping is guaranteed even if the communication fails between the relays. The scope of functions includes protection functions as well as functions for control and monitoring. The interoperable connectivity to substation control systems is given by standard protocols like IEC61850. The general concept of redundancy for protection and its communication gets completed by Ethernet redundancy protocols (PRP, HSR, RSTP) and thus increases the total system availability. Integrated functions for commissioning help and easy settings lead to short commissioning times.
