Distribution Trainer
Product Code : EL-EPP-11346
Quick Answer: The Distribution Trainer is a two-panel console for studying electrical power distribution, from basic circuits on the upper panel to balanced and unbalanced three-phase systems on the lower panel. The panels carry all the current, voltage and power meters needed for the experiments.

Key Features
- Upper panel: low-voltage a.c. and d.c. supplies, lamps as loads and variable resistances as a feeder cable, for ring main, radial and regulation experiments
- Lower panel: connections to two three-phase transformers, lines and loads to simulate industrial power distribution
- Line receive transformer reduces the line voltage to 110 V, with adjustable primary tappings and a secondary star point that can be earthed
- Current transformers feed protection relays that detect line and earth currents and record fault events and disturbances
- Two relays set from their local panels; the more complex relay set locally or from a computer with the included software
- Lamps show whether circuit-breakers are open or closed; shrouded leads supplied for connecting the test circuits

About This Product
Students start with simple feeder circuits to learn ring main and radial layouts and voltage regulation, then move to the three-phase panel to study industrial distribution and its protection. Reading the fault records from the relays gives practice in fault analysis. Enquiries from Kazakhstan, Liberia, Saint Lucia, Belarus, Grenada and Antigua and Barbuda for the Distribution Trainer receive an export quotation.
Frequently Asked Questions
What can students learn on the upper panel of the Distribution Trainer?
The basics of distribution: ring main and radial circuits using the lamps and variable resistances, and the principles of regulation using the low-voltage a.c. supplies.
How are the protection relays set on the Distribution Trainer?
The two simplest relays are set from their local control panels. The more complex relay is set from its local panel or by a cable link to a computer running the included software.
