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 suits transformer theory experiments and demonstrations in B.Tech/B.E. electrical machines labs, diploma courses and ITI Electrician training. Science Lab Supplies quotes it from Ambala, India for colleges, training institutes, tender contractors and distributors alike.
Specifications
The three-limb transformer is specified row by row in the table below. In short, three identical transformers share a common core, high-voltage primary and low-voltage secondary tappings end in coloured shrouded sockets, the windings work at one volt per turn, and thermocouples monitor one phase, all inside a wheeled steel enclosure.

Applications and Experiments for the Three Phase Transformer
With the transformer, students can 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, after the basics of transformer construction on the Demonstration Transformer Model.
- Load tests and temperature rise from the thermocouples; transformer loading with lagging power factor is a topic the Electrical Inductor Load Bank 2.4 kVAR addresses.
- 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. A suitable variable supply, loads and a temperature readout for experiments can be added to the quotation if your laboratory needs them.
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, so one document covers the whole practical set-up.
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). The number of transformers and your delivery point can be sent via the contact page or noted in the enquiry cart, while tender purchases follow 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 and check each tapping quickly.
Why are thermocouples fitted?
They measure temperatures on the primary and secondary windings and the core of one phase, helping students understand the temperature specification for materials used in transformers.
Who supplies the Three Phase Mobile Transformer?
Quotations for this three-limb teaching transformer come from Science Lab Supplies in Ambala, India, for one unit on its own or for a transformer laboratory package with load banks.
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 and positioned next to the supply and loads for each practical.
