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.
Banana jack connections used throughout.
Low-voltage operation using 5:1 dry transformers.
Internally fused.
Packaging for shipment via motor freight.
#491-500 - Use/Exercise Guide (additional).
* Patch cords. * Fourteen transformers (3 varieties). * Panel-mounted voltmeter and phase rotation meter. * Use/Exercise Guide.
208 VAC, 3-phase, 60 Hz, 4-wire.
The courseware, useful in both an instructor-led or self-directed format, includes twelve illustrated, hands-on exercises.

Exercises include:
* 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.
