Transformer Trainer
Product Code : LSK-EPS-10522
Transformer Trainer (SKU LSK-EPS-10522) is a fully instrumented module for examining single-phase and three-phase power and distribution transformers, from turns ratio and connections to losses, heating and protection. It serves electrical machines and power systems practicals in B.Tech/B.E. and diploma electrical engineering. Science Lab Supplies, a laboratory equipment supplier in India, delivers the trainer from Ambala to colleges, polytechnics, training institutes, tender contractors and distributors.
Specifications
The module holds a three-phase delta-star transformer, a second fixed-ratio delta-star unit, a three-phase educational transformer and three single-phase educational transformers with tertiary windings. Educational windings work at one volt per turn and end in colour-coded shrouded sockets, with meters, loads and an auto-transformer on the panel.

Applications and Experiments for the Transformer Trainer
Students connect windings in different arrangements, load them and measure voltage, current, power and temperature. Because the educational transformers work at one volt per turn, no-load output voltage equals the number of secondary turns, which makes ratio and connection experiments easy to check.
- B.Tech electrical machines lab: turns ratio, polarity and three-phase connections.
- Regulation and efficiency under resistive, inductive and capacitive loads.
- Core and winding temperature rise, read from the thermocouples.
- Transformer protection: line and earth current, voltage and frequency faults.
- Diploma electrical: role of tertiary windings in single-phase transformers.
The trainer runs at mains voltages; use it only under trained supervision.
Standard Scope of Supply
The trainer comes with all the transformers listed above, the load bank, auto-transformer, meters, thermocouples with temperature indicator, protection relay and software, circuit-breakers with lamps, and a set of shrouded leads. A computer for programming the relay by cable is to be arranged by the user.

Frequently Asked Questions
Why do the educational transformers work at one volt per turn?
At one volt per turn, the no-load output voltage equals the number of secondary turns, so students can relate measured voltages directly to winding turns.
Can transformer temperatures be measured?
Yes. Thermocouples on the windings and core of the three-phase educational transformer and one single-phase unit feed a digital temperature indicator.
Who supplies the Transformer Trainer?
Science Lab Supplies supplies the trainer from Ambala, India, for college laboratories and tender orders.
How are the relay settings made?
The relay is set from its local control panel, or through a cable link to a suitable computer running the included software.
