Transformer Connections Trainer

#491

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 Transformer Connections Trainer represents a safe, inexpensive, efficient, yet realistic alternative to paper-based learning and full-voltage field experience.

FEATURES 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. Overall size of 33"L x 29"W x 38"H (125 lbs). Packaging for shipment via motor freight.

COURSE CONTENT 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 effect 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.
