Transformers are used in all power classes both in industry and in domestic
appliances. They are used for the conversion of voltages and current. The
training system is based on transformers with a power rating of 1000 VA. Training
topics covered:
- Complete and simplified equivalent circuits; measurement of the individual
variables
- Transformation of current and voltage
- Measuring the rush current using an oscilloscope
- Measurement and calculation of the no-load values
- Measurement and calculation of the short-circuit values
- Measurements with a variable load R, L & C
- Determining the efficiency
- Evaluating the measured values
- Phase angle between primary and secondary windings and the effect of
asymmetric loading in the circuit groups Yy, Yd, Yz, Dy
