AEL-TPTT Three-Phase Transformer Application
The Three-Phase Transformer Application, "AEL-TPTT", has been designed by Edibon to allow the students to learn how carry out different transformer test and how they work. With this application, the user can wire the transformer and get different vector groups. The transformer ratio depends on the transformer connection and the user will can check it.
The student can analyze in depth the transformer since he will obtain the equivalent circuit and the losses of the machine. Besides, the user will study the behavior when resistive, inductive and capacitive loads are connected. On this way, different characteristic curves can be obtained such as open circuit characteristic, efficiency curve, etc.
The AEL-TPTT includes all necessary modules in order to realize all practical exercises described before, such as a transformer, ammeters, voltmeters, a power supply module and resistive, inductive and capacitive loads. Optionally, this application can include another transformer which allows studying the transformers connected in parallel.
Optionally, this application can be acquired with the Control and Data Acquisition System of Electrical Machines, EM-SCADA. This system is designed to analyze and monitoring all voltajes, currents and performace curves of dinamyc and static electrical machines. After testing procedures, the user can obtaint result reports.
