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. Colleges, institutes, tender contractors and distributors can obtain it from Science Lab Supplies in Ambala, India.
Specifications
The three transformers are identical apart from their tertiary windings. Each has a range of high-voltage primary and low-voltage secondary tappings, all brought out to coloured, shrouded sockets, and all work at one volt per turn. Thermocouples monitor primary, secondary and core temperatures on one transformer.

Applications and Experiments for the Single Phase Transformer 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.
- Parallel operation of single-phase transformers.
- Forming a three-phase bank from three single-phase units.
- Diploma and ITI training: temperature rise and insulation material limits.
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.

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.
What are the tertiary windings for?
They help compensate for slight differences between the transformers when they are operated in parallel.
Who supplies the Single Phase Mobile Transformer?
Science Lab Supplies supplies this transformer set from Ambala, India, for laboratory purchases and tender contracts.
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.
