what is vector surge & vector shift? we have 25.3 MW(11kv)
generator & 11kv/132kv transformer, connected with with 132
kv grid.vector surge relay is tripping frequentaly.what is
permissible maximum limit for this.
Answer Posted / gobind
Whan the generator have synchronized with grid the waveform
have 120 Deg each phase but at the time of any fault
occurred in the grid system,at that time the waveform of the
grid voltage have been reduced from 120 Deg to min at that
time vector Shift Relay have operated.Permissible limit of
the vector Shift 8 Deg.
