Since winding resistance is not included as part of the transformer model, provision has been made to specify and enter transformer no−load loss. This loss is realized by introducing resistances between the nodes to which the windings are connected and local ground. 变压器的no−load损失[...

Do three-phase transformer no-load, load test, the instrument can automatically determine the wiring is correct, and shows three-phase voltage and current vector map. Single machine can do the following 100KVA distribution transformer full load current experiment; ...
Core losses occur in the steel core of the transformer due to themagnetizing currentneeded to energize the core. The magnetizing current remains the same during no-load and full load. Core losses are also known as iron losses in transformers. The core losses constitute two components: Hysteresis...
