Transformer Trainer Manufacturer,Supplier and Exporter in India
Product Code : EL-EPP-11358
Quick Answer: The Transformer Trainer is a fully instrumented module for examining single-phase and three-phase power and distribution transformers. It includes one three-phase educational transformer, three single-phase educational transformers with tertiary windings and a three-phase delta-star transformer.
Last updated: October 2026
Key Features
- Educational transformers work at one volt per turn, so the no-load output voltage equals the number of secondary turns
- All windings brought out to colour-coded shrouded sockets on the control panel
- Adjustable auto-transformer for lower-voltage experiments, plus a second fixed ratio delta-star transformer
- Selectable resistive, inductive and capacitive loads for parallel, series, delta or star connection
- Analogue and digital meters and transducers for voltage, current and power; thermocouples with a digital temperature indicator
- Current transformers on the three-phase circuits link to a protection relay that detects line, earth, voltage and frequency faults

About This Product
Students run the usual transformer tests on single and three-phase units, compare winding connections and loads, and watch winding and core temperatures as the load rises. The protection relay adds fault detection and analysis on the three-phase circuits.
Frequently Asked Questions
Which transformers are included in the Transformer Trainer?
