Partial model of three-phase transformer

Information

Partial model of a three-phase transformer, containing primary and secondary resistances and stray inductances, as well as the iron core. Circuit layout (vector group) of primary and secondary windings have to be defined.
Default values for transformer's parameters (a realistic example) are:

turns ratio n	1
nominal frequency fNominal	50	Hz
nominal voltage per phase	100	V RMS
nominal current per phase	100	A RMS
nominal apparent power	30	kVA
primary resistance R1	0.005	Ohm per phase at reference temperature
reference temperature T1Ref	20	°C
temperature coefficient alpha20_1	0	1/K
primary stray inductance L1sigma	78E-6	H per phase
secondary resistance R2	0.005	Ohm per phase at reference temperature
reference temperature T2Ref	20	°C
temperature coefficient alpha20_2	0	1/K
secondary stray inductance L2sigma	78E-6	H per phase
operational temperature T1Operational	20	°C
operational temperature T2Operational	20	°C
These values give the operational parameters:
nominal voltage drop	0.05	p.u.
nominal copper losses	300	W
