https://iec61850.tissue-db.com/tissue/1844 - Implementation of SumSwARs in 3-phase circuit breaker inaccurate
TR IEC 61850-7-500
Proposal from tissue:
"By changing the PressCond of SumSwARs from O / O to OMulti / O, three summation currents can also be mapped for a three-phase circuit breaker."
A modelling example shall be described in TF7-500 to decide if also in 3-phase CB four instances of LN XCBR shall be used.
