Description

The Distribution Transformer Trainer is a portable, hands-on trainer designed to allow students to develop the skills required to connect single- and three-phase transformers similar to those found in North American ac power networks.

The trainer contains two sets of three single-phase transformers to demonstrate three-phase transformer bank configurations such as wye-wye, delta-delta, closed delta-wye, closed wye-delta, open-wye, open-delta, etc. Each individual transformer winding is protected by a thermal-magnetic circuit breaker and designed to accept multiple faults.

The trainer is faultable in order to develop sound techniques for troubleshooting single-phase and three-phase transformer banks. Eight trainer faults are available.

The trainer is complete with a student laboratory manual written in a skill-building, performance-based format, allowing easy set-up of all laboratory exercises.

Features & Benefits

  • The trainer allows students to perform the following tasks:
    • Identify different types of transformers
    • Identify faulted transformers
    • Test for proper no-load voltage
    • Show how a three-phase transformer produces correct and incorrect motor rotation
    • Show how the ratio of the transformer windings affects the secondary output voltage
    • Show how to simulate parallel single-phase and three-phase transformers
    • Simulate a burned-out transformer in a three-phase bank, as well as the connection of the remaining transformers in open-wye and open-delta configurations to produce the correct voltage

Topic Coverage
