mAHigh : The mA value that corresponds to the highest tap position. Applicable when
reading of the tap position is made via a mA signal.
CodeType : This setting gives the method of tap position reading.
UseParity : Sets the parity check On / Off for tap position reading when this is made by
Binary, BCD, or Gray code.
tStable : This is the time that needs to elapse after a new tap position has been reported
to TCMYLTC until it is accepted.
CLFactor : This is the factor designated “a” in equation 279 . When a tap changer
operates at nominal load current (current measured on the HV-side), the ContactLife
counter decrements with 1, irrespective of the setting of
CLFactor . The setting of this
factor gives the weighting of the deviation with respect to the load current.
InitCLCounter : The ContactLife counter monitors the remaining number of
operations (decremental counter). The setting InitCLCounter then gives the start
value for the counter that is, the total number of operations at rated load that the tap
changer is designed for.
EnabTapCmd : This setting enables/disables the lower and raise commands to the tap
changer. It shall be On for voltage control, and Off for tap position feedback to the
transformer differential protection T2WPDIF or T3WPDIF.
TCMYLTC and TCLYLTC Setting group
General
Operation : Switching the TCMYLTC or TCLYLTC function On / Off .
IBase : Base current in primary Ampere for the HV-side of the transformer.
tTCTimeout : This setting gives the maximum time interval for a raise or lower
command to be completed.
tPulseDur : Length of the command pulse (URAISE/ULOWER) to the tap changer. It
shall be noticed that this pulse has a fixed extension of 4 seconds that adds to the
setting value of
tPulseDur .
