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
