Office number 218-13, 2nd floor, Iridium business Building Al Barsha1, Dubai, Dubai, United Arab. This example saves the result to a file location, then loads it into the project and adds it to a group in the layer tree. A group of like-minded highly specialized people with the skills and. The result of this example can be seen below. Group1 = QgsProject.instance().layerTreeRoot().findGroup('group1') Layer2 = QgsProject.instance().mapLayersByName('Aus_state_boundaries') # Change layer nameĮxtract1 = n("native:extractbylocation", This video covers the topic vectors: What is a vector How do vectors play a role in programming motion and physics simulation in Processinghttp://natureof. This example adds the temporary output layer to a group in the layer tree: layer1 = QgsProject.instance().mapLayersByName('ne_10m_populated_places_simple') # Change layer name To run this example you would need to only change the layer names. You can see in the screenshot how my layer tree is set up. The code example in the question is incomplete so here is a complete, reproducible example which should be self explanatory to any future readers. data(): It returns a direct pointer to the memory array which is used internally by the vector to store its owned elements. # Now insert the layer node into an existing group at the desired position (given by integer in first argument) QgsProject.instance().addMapLayer(extract1, addToLegend=False) # Add the layer to project with parameter addToLegend set to False 'OUTPUT': QgsProcessing.TEMPORARY_OUTPUT}) 'INTERSECT': QgsProcessingFeatureSourceDefinition(layer2.id(), selectedFeaturesOnly=True, featureLimit=-1, geometr圜heck=QgsFeatureRequest.GeometryAbortOnInvalid), To do that you can use the code below: extract1 = n("native:extractbylocation", Any connection point which represents the windings’ neutral point is marked 1 N or 2N.I'm not sure what you mean by "save the temporary layer", because if you want to save the result, don't use a temporary output! But I guess what you actually want is to add the resulting temporary layer to the project, rename it and add it to a group in the layer tree. If the neutral point is connected to separate terminals, the code should be YN or ZN for the high voltage side and yn or zn for the low voltage side.Ĭommon to all the connection types is that the transformer’s phase terminals are marked 1U, 1V and 1W on the high voltage side and 2U, 2V and 2W on the low voltage side. ![]() ![]() Star, delta or zigzag connection is indicated by the letters Y, D and Z for the side with the highest voltage and y, d and z for the side with the lowest voltage. Three-phase transformers can have their windings connected in various ways: star, delta or zigzag connection.The connection type must be specified on the transformer’s rating plate. The transformation ratio is calculated as equal to the ratio between the main primary and secondary voltages with no load independently of the ratio between the numbers of turns. ![]()
