Application manual
LowVoltTap: This setting is used to set the position number of tap changer at possible
minimum voltage.
The following settings are required to perform the calculation of top oil temperature
using monthly model of ambient temperature when AMBVALID is low:
JanAmbTmp: This setting is used to set the January month average ambient
temperature.
FebAmbTmp: This setting is used to set the February month average ambient
temperature.
MarchAmbTmp: This setting is used to set the March month average ambient
temperature.
AprilAmbTmp: This setting is used to set the April month average ambient temperature.
MayAmbTmp: This setting is used to set the May month average ambient temperature.
JuneAmbTmp: This setting is used to set the June month average ambient temperature.
JulyAmbTmp: This setting is used to set the July month average ambient temperature.
AugAmbTmp: This setting is used to set the August month average ambient
temperature.
SepAmbTmp: This setting is used to set the September month average ambient
temperature.
OctAmbTmp: This setting is used to set the October month average ambient
temperature.
NovAmbTmp: This setting is used to set the November month average ambient
temperature.
DecAmbTmp: This setting is used to set the December month average ambient
temperature.
The hot spot temperature calculation is done by estimating the temperature rise
between the hot spot and the top oil. This difference is due to stray losses, local oil
flows and additional paper on conductor. The function has the following settings
related to hot spot to top oil temperature gradient calculation.
HPTmpRiseW1: This setting is used to set the hot spot temperature rise of winding 1
above ambient temperature in K (Kelvin).
HPTmpRiseW2: This setting is used to set the hot spot temperature rise of winding 2
above ambient temperature in K (Kelvin).
