The SIPROTEC Compact 7RW80 is a numerical, multifunction relay for connection to voltage transformers. It can be used in distribution systems, on transformers and for electrical machines. If the SIPROTEC Compact 7RW80 detects any deviation from the permitted voltage, frequency or over excitation values, it will respond according to the values set. The relay can also be applied for the purposes of system decoupling and for load shedding if ever there is a risk of a system collapse as a result of inadmissibly large frequency drops.An integrated load restoration function allows the re-establishment of the power system after recovery of the system frequency. The 7RW80 features “flexible protection functions”. 20 additional protection functions can be created by the user. For example, a rate-of-frequency change or a rate of- voltage change function can be created.The relay provides circuit-breaker control, additional primary switching devices (grounding switches, transfer switches and isolating switches) can also be controlled from the relay.Automation or PLC logic functionality is also implemented in the relay. The integrated programmable logic (CFC) allows the user to add own functions, e.g. for the automation of switchgear (including: interlocking, transfer and load shedding schemes). The user is also allowed to generate user-defined messages. The communication module is independent from the protection. It can easily be exchanged or upgraded to future communication protocols. Conformal coating available (NEW); Pluggable current and voltage terminals; Binary input thresholds settable using DIGSI (3 stages); 9 programmable function keys; 6-line display; Buffer battery exchangeable from the front; USB front port; 2 additional communication ports; Integrated switch for low-cost and redundant optical Ethernet rings; Ethernet redundancy protocols RSTP, PRP and HSR for highest availability; Relay-to-relay communication through Ethernet with IEC 61850 GOOSE; Millisecond-accurate time synchronization through Ethernet with SNTP
