Abstract (en)

[origin: EP2298450A1] The electrostatic precipitator has a collecting electrode (5) and a high-voltage electrode (1). A unit is provided for supplying emergency current to the high voltage electrode. The detachment of load is controlled. The unit for supplying emergency current has an irradiating unit for producing light, particularly ultraviolet light. The irradiating unit has a mercury gas discharge lamp. An auxiliary electrode (10) is provided which is surrounded by a dielectric (15) which comprises polymer, glass or ceramic. An independent claim is also included for a method for separation of dust with electrical resistance.
