Displays available measurements per breaker arrangement (instances of
BH_LINE_AIL). The measurements show the states of the various disconnectors,
breakers and earthing switches.
Interlock one and a half circuit breaker line B BH_LINE_B
Main menu/Test/Function status/Control/Apparatus control/
Interl11½CBLineB/BH_LINE_B:x
Displays available measurements per arrangement (instance of BH_LINE_B)
showing conditions for breakers, disconnectors and earthing switches in the
arrangement. For example QA1CLREL with boolean output 1 means that the
closing of breaker QA1 is permitted. (REL=release, ITL=interlock, OPTR=opened
transmission, CLTR=closed transmission)
Interlock, double circuit breaker bus A DB_BUS_A
Main menu/Test/Function status/Control/Apparatus control/
InterlDoubleCBBusA/DB_BUS_A:x
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 DB_BUS_B
Main menu/Test/Function status/Control/Apparatus control/
InterlDoubleCBBusB/DB_BUS_B:x
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 DB_LINE
Main menu/Test/Function status/Control/Apparatus control/
InterlDoubleCBLine/DB_LINE:x
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 ABC_LINE
Main menu/Test/Function status/Control/Apparatus control/InterlLineBay/
ABC_LINE:x
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.
