Custom functions
Customize SIPROTEC 7RW80 with flexible protection functions. Create up to 20 additional functions, like rate of change of frequency or reverse power, to tailor your operational requirements.
Why SIPROTEC 7RW80?
The SIPROTEC 7RW80 is a numerical, multi-function relay for voltage and frequency protection ideal in distribution systems, on transformers and for electrical machines by connecting it to voltage transformers.
Address and prevent critical issues like deviations from permitted voltage, frequency or overexcitation values, and system collapse from large frequency drops. The relay responds to your defined values to enable system decoupling and load shedding. An integrated load restoration function helps re-establish power after frequency recovery.
Create up to 20 additional flexible protection functions for your application needs. Use the integrated programmable logic (CFC) to add custom functions to automate switchgears and streamline operations. An independent communication module provides easy upgrades and future-proof connectivity.
Key benefits
Respond to voltage and frequency deviations
Detect and respond to deviations from permitted voltage, frequency or overexcitation values according to your settings. Take rapid action to maintain system stability and prevent damage to your critical equipment.
Prevent system collapse
Apply the relay for system decoupling and load shedding when there is a risk of system collapse. An integrated load restoration function re-establishes the power system after frequency recovery.
Improve protection
The SIPROTEC 7RW80 provides multi-stage voltage and frequency protection for enhanced feeders. Use it for generators and transformers for defective voltage/frequency control, full load rejection or islanding operations.
