Geothermal power station in Insheim
Insulated lightning protection for explosive areas with the OBO isCon and isFang systems
The boreholes of the geothermal power plant in Insheim reach deep into the earth. They provide access to water at a temperature of 165 °C, which has been conveyed from strata at depths of up to 3,600 metres. All the core components of this futuristic plant, such as the turbine, generator, heat exchanger and condenser, are protected with an insulated lighting protection system from OBO.
The operators, Pfalzwerke geofuture GmbH, employed the company Adams Blitzschutz-Systeme GmbH to implement an insulated lightning protection system according to the risk analysis. In so doing, the plant protection had to be implemented according to the technical regulations for operational safety TRBS 2152 Hazardous, potentially explosive atmosphere Part 3: Avoidance of ignition of hazardous, potentially explosive atmospheres. In all the areas of the building, except the transformer station, Adams Blitzschutz GmbH carried out its work together with OBO. The insulated arrestor OBO isCon and OBO isFang air-termination system were used.
Andreas Wiedenmann (BEx specialist) of Adams Blitzschutz-Systeme GmbH prefers to use OBO lightning protection systems on account of their rapid mounting: “This allows us to make considerable time-savings compared to conventional lightning protection.” OBO also received good marks from the lightning protection specialists for its planning and implementation work. The customer was also very satisfied with the result. Since November 2012, Pfalzwerke in Insheim has obtained enough clean energy to supply 8,000 households – and is well protected, thanks to OBO lightning protection systems.
