The Sangari ET series is a modular electrical-engineering training platform built around virtual instrumentation. The ET300 base system - a measurement interface with a full suite of virtual instruments (oscilloscope, spectrum analyzer, Bode plotter, function generator, adjustable three-phase supply) plus experimenter modules that accept plug-in experiment cards - hosts a family of course packages, each pairing hands-on experiment cards with guided multimedia courseware. The courses cover three-phase systems, measurements with the multimeter, electrical network analysis, and sensor measurement technology for non-electrical quantities: temperature, pressure and force, and displacement, angle and rotational speed. Every experiment runs at safety extra-low voltage, faults can be switched in by relay for diagnosis exercises, and all measured data is acquired, plotted and evaluated on the PC - one workstation carries an entire electrical-engineering lab curriculum.
Direct current circuits Ohm's law, resistors in series and in parallel Voltage divider with the potentiometer Single-phase alternating current circuits Behaviour of a coil in an AC circuit, with the fluorescent tube in parallel Charging and discharging a capacitor Galvanic separation with the 1:1 laboratory transformer Switching with a DC relay and with an AC relay Three-phase circuits Resistors in star and in delta Phase and line quantities Starting and loading a DC motor Electromagnetism with the coil and the iron rod Measurement with the digital multimeter, voltage, current, resistance and temperature Continuity and diode testing Fault finding, from the faults the selector switch introduces
OpenA modular apparatus for the study of programmable logic controllers and operator panels. Students wire a PLC and an HMI touch panel with safety leads to push-buttons and switches, a limit switch, a PT100 sensor, light and wind sensors, contactors, indicator lights and three 230 V wall lights. They write the control program in ladder diagram, set up the Ethernet network and build the operator screens.
