General current and voltage protection CVGAPC

Main menu/Test/Function status/Multipurpose protection/
GeneralCurrentVoltage(GAPC)/CVGAPC:x
Displays available instances of CVGAPC with a number of output quantities per
instance. These include error signals from overcurrent functions, trip and start
signals from overcurrent, undercurrent, overvoltage and undervoltage. There is a
block signal caused by second harmonic detection. The directional mode of OC1
and OC2 is shown as is low voltage for directional polarization. The current and
voltage as well as measured current multiplied by cos Phi and the angle between
voltage and current are also shown here.

Secondary system supervision

Values for Current circuit supervision and Fuse failure supervision are found under
Secondary circuit supervision. Fail and alarm detection information is available
together with various start and current data.

Current circuit supervision CCSRDIF

Main menu/Test/Function status/Secondary system supervision/
CurrentCircuitSupervision(RDIF,87)/CCSRDIF:x
Displays available instances of CCSRDIF with a number of measurements per
instance indicating the detection of current circuit failure and alarm operation.

Fuse failure supervision SDDRFUF

Main menu/Test/Function status/Secondary system supervision/
FuseFailure(RFUF)/SDDRFUF:x
Displays available instances of SDDRFUF with some measurements per instance
indicating start status.

Control

Apparatus control

Bay control QCBAY
Main menu/Test/Function status/Control/ApparatusControl/BayControl/
QCBAY:x
Displays available instances of the function QCBAY with three measurements per
instance. The operator place allocation (PSTO) measurement has an integer as
output data, whereas the Update of position is blocked (UPD_BLKD) and Function
is blocked for commands (CMD_BLKD) have boolean output data.
