Abstract

In order to obtain radiated emission characteristics from the power line, we measured the degree of unbalance to the earth and a leaked electric field from power line in high frequency band. The calculation model of power line is made by 4-terminal pair network theory, which has circuit constant as chain matrix of distributed constant on transmission line. The calculated value of TCTL (transverse conversion transmission loss) was mostly in agreement with measured value and then the validity of the calculation methods for TCTL was confirmed. The leaked electric field increases about 20 dB by grounding one of the pair line.
