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 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 MOD.3190 Single Phase Transformer Primary and secondary windings are divided in several sections to allow many possibilities of connections. 220/110V primary/secondary. Primary: 2x110V ac; Secondary: 2x55V ac; Power: 300VA; Frequency: 50-60Hz; Dimensions: LxWxH: 25x25x15 cm; Weight: 4kg;     MOD.3195 Three-phase Transformer Three phase transformer realised in didactical version. Each primary and secondary windings are divided in two sections to allow many possibilities of connection including zig-zag.
