Overview
The “Phase sequence switchover” function enables correct execution of the protection of the device and supervision functions, independently of the phase sequence of the phases in a system or system section.
For more detailed information on “Phase sequence switchover” function, refer to SIPROTEC 5 devices, V8.30 & higher manuals.
