GC Open CB [G36]
This menu specifies the open-circuit detection parameters.
Open I< [G361]
Current detection level for open circuit.
Open Ttrip [G362]
Open circuit detection trip time.
11.12.4 Grid Monitor [G90]
These menus give the state of grid by presenting measured
grid voltages, grid frequency etc. These menus are only read-
out menus for reflecting the grid status. On power-up, if
PLL's could not lock then the values in these menus start
blinking in order to indicate the non-locked PLL's.
Phase Voltages [G91]
Amplitude of phase voltages i.e. U1, U2 and U3.
Line Voltages [G92]
Amplitude of line voltages i.e. U12, U23 and U31.
Symmetrical Voltages [G93]
Amplitude of symmetrical voltages i.e. U+, U- and U0.
Grid Frequency [G94]
