Scott T transformer FEA simulation
Transformer consists of 2 single phase transformers connected in a special way. The unit allows to convert 3-phase voltage to two single-phase voltages.
Plane-parallel problem of AC magnetics.
Voltage (RMS) U=36 V,
Frequency f=50 Hz,
Core permeability μ=1000,
Copper conductivity g=56 MS/m,
Transformer1: N1=168 (with central tap), N2=168,
Transformer2: N1=145, N2=168.
Calculate input currents and output voltages in open circuit mode.
The large resistance R=10 kOhm is connected to the secondary winding. It is used to measure output voltage.
|Winding name||Voltage, U||Phase current, I|
|A||36√2 @ 0° V||1.95 @ -89° A|
|B||36√2 @ 120° V||1.94 @ 31° A|
|C||36√2 @ 240° V||1.94 @ 150° A|
|p||88 @ 0° V||-|
|q||88 @ 90° V||-|
