The Van Der Hoofden test head allows to determine the human exposure to electromagnetic fields caused by luminaries in the frequency range 20kHz to 10MHz. The measurement is based on IEC 62493 Ed. 2.0: 2015-03.
Through different ways of coupling between luminaries and humans, a level of exposure of a person to electromagnetic fields can be derived. One part of the exposure is based on capacitive coupling between lighting equipment and person. This creates induced internal electric field that must be evaluated using an EMI receiver and a Van Der Hoofden test head.
VDH 30 consists of electrically conductive sphere with 210mm diameter, connection line of 300mm length, protection network for the EMI receiver and wooden tripod.
