7.3. Investigations of the occurrence of spark discharges and contact currents

The occurrence of contact currents in daily life, especially in the vicinity of power supply facilities, is to be investigated. On account of the expected higher ground field strengths, HVDC installations are to be included into the analysis as far as possible. Moreover, dosimetric models for various scenarios and population groups are to be developed which can be used for specifying the electric field strengths for the various tissues within the body when spark discharges and contact currents occur.
