The foundation for the economic success of a biogas plant is already laid at the beginning of the design stage. The same applies to the selection of suitable and cost-effective protection measures to prevent lightning and surge damage.
To this end, a risk analysis must be performed in line with the EN/IEC 62305- 2 standard (risk management). An important aspect of this analysis is to prevent or limit a hazardous explosive atmosphere (see the German Technical Rules for operational safety/hazardous substances, TRBS 2152-2). If the formation of an explosive atmosphere cannot be prevented by primary explosion protection measures, secondary explosion protection measures must be taken to prevent ignition of this atmosphere. These secondary measures include a lightning protection system.
