Distribution Trainer
Product Code : LSK-EPS-10524
Distribution Trainer (SKU LSK-EPS-10524) takes students through electrical power distribution, from basic feeder, ring main and radial circuits to balanced and unbalanced three-phase systems with transformers, lines and protection relays. It fits power distribution and protection practicals in B.Tech/B.E. and diploma electrical courses. Universities, polytechnics, technical institutes, tender contractors and distributors can have it quoted by Science Lab Supplies, an Ambala, India business.
Specifications
The distribution trainer table lists one feature per row. In short, an upper panel teaches basics with low-voltage a.c. and d.c. supplies, lamps as loads and resistances as feeder cables, while a lower panel builds three-phase distribution with two transformers, lines, loads, meters and three protection relays.

Applications and Experiments for the Distribution Trainer
On the upper panel students can wire feeders as ring main or radial circuits and see how voltage regulation changes with load. On the lower panel they can build a three-phase distribution link with transformers and lines, apply faults and study how relays protect it.
- Diploma and ITI Electrician training: ring main and radial circuit principles.
- Voltage regulation along a feeder with low-voltage a.c. supplies, a topic taken to long lines on the Transmission Line Simulator.
- B.Tech power systems lab: balanced and unbalanced three-phase distribution, with cable feeder protection also covered by the Feeder Management Relay.
- Earthing the star point and its effect on earth fault protection.
The lower panel works at mains-derived voltages; use it only under trained supervision.
Standard Scope of Supply
The trainer is supplied with both panels, the two three-phase transformers, lamps, variable resistances, meters, three protection relays, circuit-breakers with lamps and a set of shrouded leads. Software for programming the complex relay by cable is included, and the emergency switch, mains isolator and protection fuses are built in.

Frequently Asked Questions
What is the difference between the two panels?
The upper panel teaches distribution basics with low-voltage supplies, lamps and resistances. The lower panel simulates industrial three-phase power distribution with two transformers, lines and loads.
How are the relays programmed?
The two simpler relays are set from their local control panels. The more complex relay is set locally or through a cable link to a suitable computer running the included software.
Who supplies the Distribution Trainer?
The trainer is quoted by Science Lab Supplies from Ambala, India, for colleges, training institutes and tender contractors, and a load bank or relay can be listed on the same quotation.
What voltage does the receive transformer give?
The line receive transformer steps the line voltage down to 110 V. Its primary tappings are adjustable and its secondary star point can be earthed.
