Interlock, double circuit breaker bus A
Main menu/Test/Function status/Control/Apparatus control/
InterlDoubleCBBusA/IB
The outputs from this function show when closing of disconnectors and breakers is
allowed and when it is not. It also shows whether QB1 is opened or closed and
indicates the validity of its switch status. There are several output values.
Interlock, double circuit breaker bus B
Main menu/Test/Function status/Control/Apparatus control/
InterlDoubleCBBusB/IC
The outputs from this function show when closing of disconnectors and breakers is
allowed and when it is not. It also shows whether QB1 is opened or closed and
indicates the validity of its switch status. There are several output values.
Interlock, double circuit breaker line
Main menu/Test/Function status/Control/Apparatus control/
InterlDoubleCBLine/IA
There are some instances of this function with some outputs per instance showing
whether switching of disconnectors QB9, QC3 and QC9 is permitted.
Interlock line bay
Main menu/Test/Function status/Control/Apparatus control/InterlLineBay/IF
Displays available instances of the function IF with several boolean outputs per
instance. These indicate for which disconnect devices closing and switching of is
allowed and also indicate the status and validity of devices. For example, the
measurement named QB12OPTR indicates whether or not QB1 and QB2 are in the
open position. If the output for this measurement is 1 then QB1 and QB2 are in the
open position. A zero indicates that they are closed.
Interlock, transformer bay
Main menu/Test/Function status/Control/Apparatus control/
InterlTransformerBay/IE
Shows available instances of the function with several measurements per instance.
The measurements indicate which breakers and disconnectors are permitted to open
and/or close, the status of the disconnect devices and switch status validity. For
example, the measurement named VPQB2TR indicates with output value 1 that the
switch status of disconnector QB2 is valid.
