## Phasor Diagrams & Testing Transformer

The resulting equivalent circuit is known as the exact equivalent circuit. This circuit can be used for the analysis of the behavior of the transformers. As the no-load current is less than 1% of the load current a simplified circuit known as ‘approximate’ equivalent circuit is usually used, which may be further simplified to the one. On similar lines to the ideal transformer the phasor diagram of operation can be drawn for a practical transformer also. The positions of the…
