This is a high voltage transformer (53kV) and rectifier that is used to power an Electrostatic Precipitator. The schematic shows a jumper between terminals H1 and H2 with a label "Remove jumper for half wave operation". Can anyone explain the benefit of operating the rectifier at half-wave rectification?

Also, the schematic shows 2 separate surge arrestors. Why is this?

Large plate precipitators generally require a continuous DC source, hence, full wave. Older, smaller plate precipitators typically use a pulsed DC source. Half wave rectification accomplishes this.

Large Plate precipitators are generally more efficient.

  • can u explain what 45 kv DC full load meaning? – engineer Oct 20 '17 at 17:05
  • It appears that that is just the continuous full load voltage rating of the rectifier, but that it can handle peak voltages of 75 kV before breaking down. – R Drast Oct 23 '17 at 03:21
