Three-phase Mobile Transformer
- The Three-phase Mobile Transformer is an essential tool for experiments and demonstrations of transformer theory.
- It consists of three identical transformers on a common core to create a three-limb, three-phase transformer.
- All tappings connect to coloured, shrouded sockets for safety.
- To show transformer principles clearly, the transformers operate as one volt each turn.
- The transformer is inside a steel enclosure, which has small wheels for ease of mobility.
- This means that the no-load output voltage is the same as the number of turns on the secondary.
- For a typical test, students connect the primary and secondary winding to suit their experiments.
- All tappings are accessible, so students may link the windings to suit any of the common three-phase connections.
- The transformer has a selection of high-voltage (primary) and low-voltage (secondary) tappings to select a range of input and output voltages.
