| Popis: | The induced toroidal electric field is measured optically by using a Pockels device. The electric field induced by the conventional transformer method is generally smaller than 100V/cm and, in this works, a transformer with the multiple primary coils has been used for the field induction. On the measurement the electric field is much smaller in the Pockels device than in air due to the large permittivity (εs-56). In order to avoid the decrease in the sensitivity the measurement system has been put in water (εs-82). The retardation by Pockels effect is of the order of 10-2 and the measurement values of the induced electric field are 40-200V/cm which are agreed with those calculated from one turn voltage within about 20%. |
