Siemens 7SK80 SIPROTEC Compact is a multi-functional motor protection relay is designed for protection of asynchronous motors of all sizes. The relays have all the required functions to be applied as a backup relay to a transformer differential relay.

The SIPROTEC 7SK80 features “flexible protection functions”. Up to 20 additional protection functions can be created by the user.

Therefore protection of change for frequency or reverse power protection can be realized, for example.

The relay provides circuit-breaker control, further switching devices and automation functions. The integrated programmable logic (CFC) allows the user to add own functions, e.g. for the automation of switchgear (interlocking). The user is also allowed to generate user-defined messages.

The 7SD80 Line differential protection relay has been conceived for selective line protection of power cables and overhead lines up to 24km for all kind of star point configurations. The implemented phase comparison algorithm is a fast and stable method for line protection in industry and distribution grids. The protection interface communication of 7SD80 Line differential protection relay is carried out directly without external equipment over copper wires, optical fibers or both in redundancy.The wide scope of non-directional 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 by means of 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.

Detail Protection interface communication Data exchange of the differential protection function takes place by means of digital communication via integrated two-wire interface and / or an integrated fiber-optic interface. By parallel use of both options, communication redundancy can be realised, therefore.Communication via the protection interface can further be used to send an inter-tripping command to the circuit-breaker at the opposite end, and to exchange at the same time up to 16 freely assignable binary signals between the 7SD80 relays.
