Single Phase Mobile Transformer
Product Code : LSK-EPS-10529
Single Phase Mobile Transformer (SKU LSK-EPS-10529) is a set of three single-phase teaching transformers, each in its own steel enclosure on a wheeled frame, which can be used individually or linked into one three-phase bank. Extra tertiary windings support parallel-operation studies. It serves electrical machines practicals in B.Tech/B.E., diploma and ITI Electrician courses. For colleges, institutes, tender contractors and distributors, the set is available on quotation from Science Lab Supplies of Ambala, India.
Specifications
All details of the single-phase transformer set are given row by row below. In short, three transformers, identical apart from their tertiary windings, offer high-voltage and low-voltage tappings on coloured shrouded sockets, work at one volt per turn and sit in separate steel enclosures on a wheeled frame.

| Supplied by | Science Lab Supplies, Ambala, India |
Applications and Experiments for the Single Phase Transformer Set
With the set, students can test each unit as a single-phase transformer, run two in parallel using the tertiary windings to compensate for small differences, or connect all three as a three-phase bank. Output voltage equals secondary turns at no load, which keeps calculations simple.
- B.Tech electrical machines lab: single-phase ratio, polarity and load tests, with unbalanced loading a topic the Power Factor Load Bank also covers.
- Parallel operation of single-phase transformers.
- Forming a three-phase bank from three single-phase units.
- Tap selection, compared with the fixed 2, 3, 8 and 12 V AC outputs of the Multitap Transformer.
- Diploma and ITI training: temperature rise and the temperature specification of transformer materials.
The transformers operate at mains-level voltages; make connections only with the supply isolated and under supervision.
Standard Scope of Supply
The set comprises three single-phase transformers in separate steel enclosures, the wheeled frame they fit onto, the tappings and tertiary windings on shrouded sockets, and the thermocouples. Supplies, loads and a temperature readout for experiments are quoted separately if required.
Packing, MOQ and Lead Time
We can quote one set or multiple sets for parallel practical groups. Each quotation states packing, delivery time and price for the requested quantity, and the three-phase version or load banks can be listed on it too, keeping the whole order on one document.
Science Lab Supplies holds an Importer-Exporter Code and can ship to buyers in Rwanda, South Africa, Qatar, Sri Lanka, Vietnam and Malaysia.

Frequently Asked Questions
Can the set be used as a three-phase transformer?
Yes. The three units work as individual single-phase transformers or can be connected together to form a single three-phase transformer, using the accessible tappings on each unit.
What are the tertiary windings for?
They help compensate for slight differences between the transformers when they are operated in parallel; apart from these extra windings, the three units are identical.
Who supplies the Single Phase Mobile Transformer?
Science Lab Supplies handles quotations for this three-transformer set from Ambala, India, for a single machines laboratory, for several practical groups or as part of a tender contract.
How does it differ from the Three Phase Mobile Transformer?
The three-phase model has three identical transformers on one common core in a single enclosure, while this set keeps three separate transformers with tertiary windings.
