Low Cost DC High Voltage Generator for Industries and Laboratories

This work describes the details of high voltage D.C. power supply whose output is 60 kV, whereas its input voltage is 1-Φ 50 Hz 5 kV of sinusoidal waveform. This test set is suitable for field testing of high voltage cables, as a prime D.C source for very low frequency high voltage test, oscillating wave technique and impulse voltage charging unit due to its light weight and portability. In this study, we constructed a prototype high voltage power supply based on design, simulation and implementation of hardware work in laboratory. The simulation work has been done by using Mat. Lab. Version 7.0 software. This developed equipment will be very useful for field testing of HV cables of different voltage grade, as a prime DC source for VLF and OW testing set and charging unit of impulse generators.
