Continuous recording
Selecting continuous recording option enables recording of all transitions without pressing OMEGA in
each tap position. After initial resistance measurement is done and a message is shown, it is necessary
to change the tap positions. The graph is displayed after the first measurement is done and it shows
dynamic resistance value in real-time during the test. At any time, the last 20 seconds of measurement
will be shown. Once STOP is pressed, all the transitions (OLTC dynamic resistance graph) will be
displayed. The DV-Win measures transition time for each transition and displays results in the results
table.
Tools - Options
Advanced settings for the tap changer graphic function. These settings are recommended for advanced
users.
Test current
It is possible in DV-Win software to enter test current values in two ways. The first way is drop down
menu where you can choose test currents like they are set in device (5 mA, 10 mA, 50 mA, 100 mA, 500
mA, 1 A, 2 A, 5 A, 10 A, 15 A, 25 A, 40 A, 60 A
). The second option is to choose “Tools”, then “Options”
and then by checking “Test current step 1 A” and OK button it is possible to set all test current from 4 A
to 60 A in 1 A step.
Advanced OLTC settings
To set sensitivity of the on load tap changer transition detection. Default value is 1,5%. Decrease this
value in order to increase sensitivity. In this case possible noise could be detected instead of the
transition.
