1. POWER DISTRIBUTION TRANSFORMER TRAINER
The Distribution Transformer Trainer Model AUP-1 is a portable, hands-on trainer designed to allow students to develop competence in completing single/three-phase transformer connections similar to those performed in the field. The trainer contains two sets of three single-phase transformers to demonstrate three-phase banking configurations, such as wye-wye, delta-delta, closed delta-wye, closed wye-delta, open-wye, open-delta, and others. Each individual transformer winding is thermally protected and designed to accept multiple faults. The Model is built to supply 240 VAC with a center tap on the secondary winding when the primary winding is connected between line and neutral instead of line to line.
List of topics cover:-
- To find the transformation ratio of a transformer by watt meter method.
- To find the transformation ratio of a transformer on load by the ampere meter method.
- Polarity test of transformer.
