TCMYLTC or TCLYLTC (84) function block for the same transformer as TR8ATCC
(90) block belongs to.
There are 10 binary signals and 6 analog signals in the data set that is transmitted from
one TR8ATCC (90) block to the other TR8A
TCC (90) blocks in the same parallel
group:
Table 56: Binary signals
Signal Explanation
TimerOn This signal is activated by the transformer that has started its timer and is going to
tap when the set time has expired.
automaticCTRL Activated when the transformer is set in automatic control
mutualBlock Activated when the automatic control is blocked
disc Activated when the transformer is disconnected from the busbar
receiveStat Signal used for the horizontal communication
TermIsForcedMaster Activated when the transformer is selected Master in the master-follower parallel
control mode
TermIsMaster Activated for the transformer that is master in the master-follower parallel control
mode
termReadyForMSF Activated when the transformer is ready for master-follower parallel control mode
raiseVoltageOut Order from the master to the followers to tap up
lowerVoltageOut Order from the master to the followers to tap down

Signal Explanation
voltageBusbar Measured busbar voltage for this transformer
ownLoadCurrim Measured load current imaginary part for this transformer
ownLoadCurrre Measured load current real part for this transformer
reacSec Transformer reactance in primary ohms referred to the LV side
relativePosition The transformer's actual tap position
voltage Setpoint The transformer's set voltage (
VSet
) for automatic control
Manual configuration of VCTR GOOSE data set is required. Note that
both data value attributes and quality attributes have to be mapped. The
following data objects must be configured:
• BusV
• LodAIm
• LodARe
• PosRel
