Voltage plausibility
General notes
If there is a connection between System A and System B based on breaker feedbacks, the
monitoring function compares the status 󰈢ags of System A (logical command variable
02.11) and System B (logical command variable 02.05) on same condition. Additionally, if
both systems are okay, the monitor expects to see a phase angle between both systems
less than +/- 10°. The intension of this monitor is to detect wiring failures or blown fuses.
An alarm will be initiated if
• the status 󰈢ags of System A (02.11) and System B (02.05) do not have the same
condition
• the status 󰈢ags of System A (02.11) and System B (02.05) have the same condition
but the phase angle between both systems is too big
If this protective function is triggered, the display indicates "Voltage mismatch" and the
logical command variable "08.47" will be enabled.
