Multi-purpose low cost DC high voltage generator (60 kV output), using Cockcroft-Walton voltage multiplier circuit

  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...

Time study and skidding capacity of the wheeled skidder Timberjack 450C

  For evaluating the efficiency of wheeled skidder Timberjack 450C in ground skidding system, a forest in Caspian region was selected. In the research area, trees were logged downhill to the depot by a wheeled skidder Timberjack 450C. The work elements of a skidding cycle from stump area to roadside depots were travel empty, establishment time, release the cable winch, hooking, winching, travel loaded,...
