E.M.M.S. Electrical Machines Modular System 0,3 kW
Transformers 
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 300 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 noload values
 Measurement and calculation of the shortcircuit 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
