Title: Process for controlling the current supply device of an electrofilter.
Inventor: DOENIG GERHARD
IPC: H02H3/08
Filed: 1990-04-04
Abstract: A filter short circuit is detected when the primary voltage of the high-voltage transformer drops below a specified minimum value and does not rise above the specified minimum value during a specified delay period and a filter current is greater than a specified minimum current. No current is drawn from the external current supply for a variable time delay when a filter short circuit is detected. A filter short circuit count is incremented when a filter short circuit is detected. When the count exceeds a specified, variable limit within a specified, variable time span, the indirect converter is disconnected.
