Transformer Trainer

Product Description

Description:

The Transformer Trainer module fully examines single phase andthree-phase power and distribution transformers.

The fully instrumentedunit includes:

1. One three-phase educational transformer
   
2. Three single-phase educational transformers with tertiarywindings
   
3. One three-phase delta-star transformer
   

All windings of the educational transformers connect to colour-codedshrouded sockets on the control panel. The educational transformers work at onevolt each turn, so the no-load output voltages are the same as the number ofsecondary turns. An adjustable autotransformer allows lower voltage experiments.The module includes a second fixed ratio delta-star transformer for extraexperiments. The control panel includes all the analogue and digital meters andtransducers needed to measure electrical voltage, current and power for alltransformer tests. Also included are selectable resistive, inductive andcapacitive loads, which can connect in parallel, series, delta or star connection.
