RMO60TD DV-Win Software
Set the measurement parameters such as:
- Connections
- marking of the windings of the transformer under test
- Test current
Test current
is described in the Current mode.
Resistance Compensation
is described in the Current mode.
DV-Win software enables recording of the test current values during the change of the tap changer
position and plotting recorded values. If this function is not needed, please uncheck the option "Use
OLTC Dynamic Resistance graph".
Graphic function is available in the “on-line” or “off-line” mode. Using both off-line and on-line modes, test
current values during the transition from tap to tap are shown on the graph.
Graph control window contains options and commands to control graph display. Graph is displayed in
separate window, where user can zoom in and zoom out interesting parts of the graph. Test current
values are shown on the vertical axis, and tap transitions are shown on the graph.
Before the test is started it is necessary to set the following tap changer parameters:
Standard tap changer
Before the beginning of the test it is necessary to set tap changer to the first or the last tap changer
position.
Total taps
Indicates the number of tap positions, excluding nominal positions. This could also be interpreted as the
last tap position number.
Direction
It specifies the direction of changing tap positions.
Nominal positions
It specifies whether the tap changer has nominal positions or not.
Nominal positions type
It specifies the type of nominal positions.
