Safe and automated control of experiments with a high voltage construction kit

For high voltage (HV) experiments in scientific and industrial environments flexibility is a great advantage. For this reason the HV construction kit is very popular for the generation of AC, DC and impulse voltages of up to 260 kV. A modern and flexible alternative AC-source is built with an industrial three-phase frequency converter (FC) controlled by a failsafe Programmable Logic Controller (PLC). Moreover, the FC has the advantage that voltage and frequency can be controlled separately from each other. From the three-phase output, two phases are connected via an insulation transformer and filtering system to the high voltage transformer and the rest of the experimental construction kit. The effective performance of the filtering system also enables partial discharge (PD) measurements…
