Learning objectives

By the end of this module, students will be able to:

  • Identify the main parts of a three-phase step-down transformer

  • Understand the primary winding, secondary winding, laminated core, terminals, bushings, tank, insulation, and cooling system

  • Explain how voltage transformation happens through electromagnetic induction

  • Relate the turns ratio to step-down voltage operation

  • Understand three-phase connections such as star and delta, where relevant

  • Visualise the magnetic flux path, energy transfer, losses, heating, and cooling

  • Connect transformer operation with substations, distribution networks, and industrial power systems

About the module

The full machine, part by part and in action.

A three-phase step-down transformer reduces high-voltage three-phase electrical power to a lower voltage suitable for distribution, industrial loads, and end-use systems. It is a key machine in substations, distribution networks, factories, commercial buildings, and utility infrastructure.

In this iXRLabs 3D machine module, students observe the transformer as a complete system and understand the function of each part. The working explanation shows how alternating current in the primary winding produces a changing magnetic flux in the core, which induces voltage in the secondary winding. The module explains voltage reduction using the turns ratio and shows how three-phase power is handled across the winding system.

It also introduces practical engineering concepts - core losses, copper losses, insulation, cooling, terminal connections, bushings, vector groups, load behaviour, voltage regulation, and transformer safety. It works well for machine familiarisation, classroom demonstration, virtual lab support, and power systems learning, with the 7thi AI tutor and built-in assessment throughout.

7thi and assessment in this module

7thi

7thi in this module

Students can ask 7thi about the turns ratio, flux path, star/delta connections, or any part they see in the model. 7thi answers in context, without breaking the flow.

Common questions

Questions about this module.

Book a demo
Can students take the transformer apart?

Yes. The model can be explored as a complete machine and as separated components - primary and secondary windings, laminated core, bushings, tank, and cooling fins - so learners see how the parts fit and work together.

Does it explain the working, not just the parts?

Yes. The module walks through applying voltage to the primary winding, the alternating magnetic flux in the core, induction in the secondary, and step-down voltage from the turns ratio.

What prior knowledge do students need?

Basic electrical engineering and AC fundamentals. Suitable for undergraduate Year 2 and above, and for diploma / polytechnic electrical courses.

How long is a typical session?

About 15 minutes for a full run including assessment. Faculty can assign specific scenes or the complete walkthrough.

Which headsets is this module optimised for?

HTC, Meta Quest 2 / 3 / Pro, ClassVR, and any WebXR-compatible browser. It also runs in desktop browsers without a headset.
