Before starting any test, verify the following settings in PCM600 or the local HMI
for TR1ATCC, TR8ATCC and TCMYLTC and TCLYLTC.
•
Confirm power system base quantities

.
•
Confirm that the setting for short circuit impedance
Xr2
for TR1ATCC or
TR8ATCC is in accordance with transformer data:
•
Short circuit impedance, available on the local HMI under
Main menu/
Settings/IED settings/Control/TransformerVoltageControl(ATCC,
90)/TR1ATCC:x/TR8ATCC:x/Xr2
.
•
Confirm that the setting for TCMYLTC or TCLYLTC is in accordance with
transformer data:
•
Tap change timeout duration - effectively the maximum transformer tap
change time,
tTCTimeout
, available on the local HMI under
Main menu/
Settings/IED Settings/Control/TransformerTapControl(YLTC,84)/
TCMYLTC:x/TCLYLTC:x/tTCTimeout
.
•
Load tap changer pulse duration - required length of pulse from IED to
load tap changer,
tPulseDur
, available on the local HMI under
Main
menu/Settings/IED Settings/Control/TransformerTapControl(YLTC,
84)/TCMYLTC:x/TCLYLTC:x/tPulseDur
.
•
Transformer tap range,
LowVoltTap
and
HighVoltTap
, available on the
local HMI under
Main menu/Settings/IED Settings/Control/
TransformerTapControl(YLTC,84)/TCMYLTC:x/TCLYLTC:x/
HighVoltTap
and .
•
Load tap changer code type - method for digital feedback of tap position,
CodeType
, available on the local HMI under
Main menu/Settings/ IED
settings/Control/TransformerTapControl(YLTC,84)/TCMYLTC:x/
TCLYLTC:x/CodeType
.
During the installation and commissioning, the behavior of the
voltage control functions for different tests may be governed by a
parameter group, available on the local HMI under
Main menu/
Settings/IED Settings/Control/
TransformerVoltageControl(ATCC,90)/TR1ATCC:x/
TR8ATCC:x
. These parameter settings can cause a Total Block,
Automatic Block or Alarm for a variety of system conditions
including over and under voltage, over current and tap changer
failure. It is important to review these settings and confirm the
