Fuse failure supervision SDDRFUF
Main menu/Test/Function status/Secondary system supervision/
FuseFailure(RFUF)/FSD
Displays available instances of SDDRFUF with some measurements per instance
indicating start status.
11.6.9
Control
There are large amounts of output data from the control functions. The main
categories of data are found under Synchrocheck, Autorecloser and Apparatus
control. Apparatus control has by far the largest amount of data since this includes
all the interlocking information for several different breaker arrangements.
11.6.9.1
Apparatus control
Interlocking
Main menu/Test/Function status/Control/Apparatus control/Interlocking
Displays available instances of the function with an open and a close parameter for
each disconnection device. The enable open (EN_OPEN) parameter will have the
output value one if an open operation is allowed and a zero output if an open
operation is not allowed. The conditions for an open operation are if the device is
closed, intermediate or in a bad state as defined in IEC61850. The enable close
(EN_CLOSE) parameter is subject to similar conditions.

InterlBusbarEarthSwitch/IJ
The information shown here indicates whether or not switching of the earth switch
is permitted and also indicates whether the earth switch QCis in the open or closed
position.
