This realistic training device replicates the conditions and circumstances that a utility worker encounters when making common transformer connections in the field.
A wide variety of activities can be performed at reduced voltages for safety (A 208 VAC, 3-phase source is stepped down, creating a 41 VAC, 3-phase system). Both three-phase and single-phase applications are provided. Using banana jacks, ground connections, primary connections, and secondary connections are easily made.
The training aid provides a safe, inexpensive, efficient, yet realistic alternative to paper-based learning and full-voltage field experience.
Welded steel cabinet.
Modular design, allowing for both single-phase and three-phase activities.
The courseware, useful in both an instructor-led or self-directed format, includes twelve illustrated, hands-on exercises.
* Perform single-phase transformer connections.
* Analyze transformer single phase voltages.
* Identify three-phase connections.
* Interconnect multiple transformers in Wye or Delta configurations.
* Analyze three-phase voltage readings.
* Identify “transformer turns ratio” (TTR).
* Demonstrate how capacitors affect line voltage and current.
* Demonstrate how three-phase transformer connections can produce incorrect motor rotation.
* Demonstrate how to parallel single-phase and three-phase transformers.
* Demonstrate line droop.
* Simulate a burned-out transformer in a three-phase bank.
