Three Phase Mobile Transformer
Product Code : LSK-EPS-10528
Three Phase Mobile Transformer (SKU LSK-EPS-10528) is a three-limb, three-phase teaching transformer in a wheeled steel enclosure, with every winding tapping brought out so students can build any common three-phase connection. It is used for transformer theory experiments and demonstrations in B.Tech/B.E. electrical machines labs, diploma courses and ITI Electrician training. Science Lab Supplies dispatches it from Ambala, India to colleges, training institutes, tender contractors and distributors.
Specifications
Three identical transformers share a common core to form a three-limb unit. High-voltage primary and low-voltage secondary tappings end in coloured, shrouded sockets, and the windings work at one volt per turn. Thermocouples monitor primary, secondary and core temperatures on one phase.

Applications and Experiments for the Three Phase Transformer
Students link the windings for the connection they are studying, feed the primaries from a suitable variable supply and measure output voltages with or without load. Because the no-load output equals the number of secondary turns, ratios and phase relationships can be checked at a glance.
- B.Tech electrical machines lab: star-star, star-delta, delta-star and delta-delta connections.
- Voltage ratio and tap selection on a three-limb core.
- Load tests with external loads and temperature rise from the thermocouples.
- ITI Electrician and diploma training: identifying windings and making safe connections.
The transformer is energised at mains-level voltages; connect and disconnect leads only with the supply off, under supervision.
Standard Scope of Supply
The Three Phase Mobile Transformer is supplied as a single wheeled unit as described above, with its tappings, shrouded sockets and thermocouples. The variable supply, loads and temperature readout used in experiments are not listed with it and can be added on the quotation.
Packing, MOQ and Lead Time
Price requests can cover a single transformer or several for group practicals. The quotation gives packing, delivery time and price for that number, and a load bank or the single-phase version can be added to it.
Operating with an Importer-Exporter Code, Science Lab Supplies can ship to buyers in Zambia, Rwanda, South Africa, Qatar, Sri Lanka and Vietnam. Science Lab Supplies is registered for GST (GSTIN 06ADEPJ0574F2ZU). Enquire through the contact page or the enquiry cart; for tenders, see the lab tender page.
Frequently Asked Questions
What does one volt per turn mean in practice?
The no-load output voltage equals the number of turns on the secondary, so students can read turns directly from their voltage measurements.
Why are thermocouples fitted?
They measure temperatures on the primary and secondary windings and the core of one phase, helping students understand temperature specifications for transformer materials.
Who supplies the Three Phase Mobile Transformer?
Science Lab Supplies supplies it from Ambala, India, and can quote it alone or within a transformer lab package.
How is it moved around the lab?
The transformer sits inside a steel enclosure fitted with small wheels, so it can be rolled between benches.
