Overview
In the “Voltage current 1 phase” function group, all functions can be used for protecting and for monitoring a protection object or equipment that allow a 1-phase current and voltage measurement or a zero-sequence voltage measurement via the 3-phase voltage measuring point.
For more detailed information on “Voltage current 1 phase” function group, refer to SIPROTEC 5 devices, V8.30 & higher manuals.
