Overview
The “Overvoltage protection with 3 phase voltage” function is used to monitor the permissible voltage range, protect equipment (for example, plant components, machines, etc.) against damages caused by overvoltage and decouple systems (for example, wind power supply).
For more detailed information on “Overvoltage protection with 3 phase voltage”, refer to SIPROTEC 5 devices, V8.30 & higher manuals.
