Abstract
Transformer in the electric power system as a means of transforming electrical power from high/medium voltage to low voltage. Three-phase transformers in electric power systems can be connected in a variety of relationships according to the needs of the network and consumers. Implementation in practice in the workshop is difficult to do with the condition of the availability of electricity grid voltage and the available load voltage for various types of loads. The isolation transformer module provides an alternative to the various possibilities of transformer experiments with various variations of transformer relationships and variations in load relationships under voltage conditions according to the network and consumer loads. Experiments of various transformer relationships with balanced and unbalanced loads can be carried out safely for measurement. The results of the empty load measurement show that the input voltage and output voltage show a value that is close to the same.
Keywords: transformer, power grid, electrical load
