Method to Prevent Grounding from a Silicon Rod to a Plate in Polycrystalline Silicon Reactor

A process to prevent grounding from a silicon rod to a reactor plate in a polycrystalline reactor comprising:

• providing the polycrystalline silicon reactor having the reactor plate with a plurality of silicon rod holders each separated from the reactor plate with an insulation;
• establishing an electrical circuit from the plurality of rod holders connected to a high voltage switching component further connected to an automated alternating current high potential testing equipment further connected to a ground connection on the reactor plate;
• and
• completing the electrical circuit by applying a voltage so that a current flows from the automated alternating current high potential testing equipment to the plurality of rod holders and to the ground connection;
• wherein any remaining polymer in the polycrystalline silicon reactor deposited completely or partially on the plurality of rod holders or the insulation of each of the plurality of rod holders is physically removed as the remaining polymer burns or is ejected by the energetic release caused by arcing from the plurality of rod holders to the reactor plate.
