VDH 30 Van Der Hoofden測試頭
-人體暴露在20kHz至10MHz頻率範圍內的燈具引起的電磁場
-測量基於IEC 62493 Ed。 2.0:2015-03
商品說明

VDH30 Van Der Hoofden測試頭可以確定人體暴露在20kHz至10MHz頻率範圍內的燈具引起的電磁場。測量基於IEC 62493 Ed。 2.0:2015-03。
通過燈具和人類之間的不同耦合方式,可以導出人對電磁場的暴露水平。曝光的一部分基於照明設備和人之間的電容耦合。這會產生感應內部電場,必須使用EMI接收器和Van Der Hoofden測試頭進行評估。VDH 30由直徑210mm的導電球,300mm長的連接線,EMI接收器和木質三腳架的保護網絡組成。

Van Der Hoofden Test Head

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.
