The task of this master thesis is to realize a computer based measurement system for continuously measuring and storing the voltages and currents of the inductive furnace. In this measurement system, sensors for voltages and currents are chosen and installed, sensor supplies are established, and analog signal transmission and scaling of signals are accomplished. Finally, by means of special measurement software DEWESOFT 6.3, measuring signals from the furnace unit are stored in external hard disks. These data in the hard disks can be analyzed in detail afterwards in order to evaluate operation and transient conditions.",
