Distribution Trainer
Distribution Trainer (Product Code: SLE/EPS/02) is a two-panel electrical training system used to teach low-voltage and three-phase power distribution — feeders, loads, regulation, ring main and radial circuits — in power systems laboratories at engineering colleges, polytechnics and technical institutes. Its upper panel covers distribution basics with lamps and variable resistances, while its lower panel simulates industrial three-phase distribution using two three-phase transformers, one of which steps the line voltage down to 110 V. It is made by Jain Scientific Equipments Pvt Ltd (ScienceLab), an OEM manufacturer, at its own factory in Ambala, India.
Key Details
| Parameter | Detail |
|---|---|
| Upper panel | Basics of distribution: low-voltage AC and DC supplies, a set of lamps and variable resistances |
| Feeder and load simulation | Variable resistances simulate a feeder cable; lamps simulate loads |
| Lower panel | Advanced three-phase distribution: connections to two three-phase transformers, lines and loads to simulate industrial power distribution |
| Supply transformer | Reduces the incoming supply voltage to the correct value for the experiments |
| Line receive transformer | Reduces the line voltage down to 110 V |
| Transformer connections | Adjustable primary tappings; secondary winding star point can be connected to earth |
| Metering | All current, voltage and power meters needed for the experiments are on the panels |
| Experiments | Ring main and radial circuits; principles of regulation |
| Product code | SLE/EPS/02 |
| Manufacturer | Jain Scientific Equipments Pvt Ltd (ScienceLab) — OEM |
| Country of origin | India (made in Ambala, Haryana) |
What Is the Distribution Trainer Used For?
Students start on the upper panel, where a variable resistance stands in for a length of feeder cable and lamps act as consumer loads. Wiring the feeder as a radial circuit and then as a ring main shows why the ring keeps voltage higher at the far end and keeps supply going if one section is opened. Connecting the low-voltage AC supplies and changing load makes voltage regulation — the drop between no load and full load — something students can measure rather than just calculate.
The lower panel moves the same ideas to three-phase systems. One transformer brings the incoming supply down to the correct value for the experiments, lines carry power to the loads, and the second transformer reduces the line voltage to 110 V as the receiving-end transformer. Adjusting the primary tappings and earthing the secondary star point illustrates practical choices in real distribution networks, while the built-in current, voltage and power meters mean no extra instruments are needed for the core experiments.
What to Specify When Ordering
- Your incoming mains supply (voltage, phases and frequency), which is not stated in the listing.
- Bench or floor space for the two-panel trainer.
- Whether additional load banks or transformers are wanted for extended experiments.
- Number of trainers for your laboratory.
OEM Manufacturer
Jain Scientific Equipments Private Limited, whose trading name is ScienceLab, is the OEM of the Distribution Trainer. The trainer is made and assembled at the company's own licensed factory at 449, HSIIDC Industrial Area, Saha, Ambala, Haryana, India, and each trainer ships directly from there to the customer.
Electrical engineering departments, ITIs, dealers and importers therefore get quotations, technical guidance and any later spares or repeat units straight from the manufacturer — ask us for what you need. See our company profile.

Frequently Asked Questions
What does the Distribution Trainer teach?
The Distribution Trainer teaches the basics of power distribution on its upper panel and three-phase industrial distribution on its lower panel, including feeder and load simulation, ring main and radial circuits, and the principles of voltage regulation.
How are feeders and loads simulated on the Distribution Trainer?
On the Distribution Trainer's upper panel, variable resistances simulate a feeder cable and a set of lamps simulates consumer loads, supplied from low-voltage AC and DC sources, so students can see voltage drop and load sharing directly.
What transformers are used in the Distribution Trainer?
The Distribution Trainer's lower panel connects to two three-phase transformers. One reduces the incoming supply to the correct experimental value; the other reduces the line voltage to 110 V and acts as the line receive transformer.
Are meters included with the Distribution Trainer?
Yes. The Distribution Trainer panels include all the current, voltage and power meters needed for the experiments, so students can take readings without connecting separate instruments for the standard exercises.
Who manufactures the Distribution Trainer?
The Distribution Trainer is manufactured by Jain Scientific Equipments Pvt Ltd (ScienceLab), the OEM, at its own licensed factory in Saha, Ambala, Haryana, India, and supplied factory-direct to institutions, dealers and importers in India and international markets.
What should a quotation request for the Distribution Trainer include?
A quotation request for the Distribution Trainer should give your mains voltage and frequency, the number of trainers, any extra load banks or transformers wanted and the delivery address. Send it through the contact page.
