An Introduction to the Siemens Siprotec 7RW80 Voltage & Frequency Protection Relay

A multipurpose, numerical relay for voltage transformer connections is the SIPROTEC Compact 7RW80 Voltage & Frequency Protection. Electrical machines, transformers, and distribution systems can all be used.

If any deviation from the permitted voltage, frequency, or over-excitation levels is detected by the SIPROTEC Compact 7RW80. Moreover, it will respond to the preset values. In addition, the relay can be used for load shedding and system decoupling if excessive frequency decreases represent a danger of system failure. The power system can be restored after the system frequency has recovered thanks to an incorporated load restoration feature.

The 7RW80 has adaptable protective features. It is possible to design a rate-of-voltage change function or a rate-of-frequency change function, for instance. In addition to controlling circuit breakers, the relay can also control other principal switching devices. Such as isolating, transferring, and grounding switches. The relay also incorporates automation or PLC logic features. The user can add their operations, such as automating switchgear (including load shedding, transfer, and interlocking schemes). Using the integrated programmable logic (CFC). Additionally, user-defined messages can be generated by the user.

Protection Function:
