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. Topic Coverage Distribution Transformer Trainer Transformer Polarity and Terminal Markings Single-Phase Transformers Supplying Single-Phase Loads Single-Phase Paralleling Three-Phase Banking of Single-Phase Transformers 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 2 Festo Didactic
