Single Phase Mobile Transformer
Product Code : EL-EPP-11351
Quick Answer: The Single Phase Mobile Transformer set is three single-phase transformers, each in its own steel enclosure, carried on a frame with small wheels. They work as three individual transformers or connect together as one three-phase transformer.
Last updated: October 2026
Key Features
- Three single-phase transformers in separate steel enclosures on a wheeled frame
- Wound at one volt per turn, so no-load output voltage equals the number of secondary turns
- High-voltage (primary) and low-voltage (secondary) tappings plus tertiary windings
- All tappings brought out to coloured, shrouded sockets for linking to common single and three-phase connections
- Tertiary windings help compensate for slight differences between transformers in parallel
- Thermocouples on the primary windings, secondary windings and core of one transformer

About This Product
Because each transformer gives one volt per turn, students can read the turns ratio straight from the output voltage. Linking the three units in different single and three-phase arrangements, running them in parallel and logging winding and core temperatures covers the main experiments of transformer theory. Educational Instrument can dispatch the Single Phase Mobile Transformer to laboratories in Belize, North Macedonia, Gabon, Jordan and Equatorial Guinea.
Frequently Asked Questions
Can the Single Phase Mobile Transformer be used as a three-phase transformer?
Yes. The three transformers work as individual single-phase units or can be connected to form a single three-phase transformer.
Why are the transformers wound at one volt per turn?
So the no-load output voltage equals the number of turns on the secondary, which makes transformer principles easy to see.
