Transmission Line

The insulation of the power transmission systems experience stresses due to overvoltages and hence the insulation design of Extra High Voltage and Ultra High Voltage systems depend on the switching overvoltages rather than lightning overvoltages. Insulation failure probability under switching overvoltages is the main impressive concern in the estimation of switching surge flashover rate. .

    This data set is about the measurement of the statistical electromagnetic field coupling to several shielded coaxial cables. The lines are aligned in parallel to a wall of a reverberation chamber. With a vector network analyzer, the coupled voltage between the inner conductor and the cable shield is measured for different stirrer positions over a wide frequency range. For comparison, the coupled current on the cable shield is calculated based on transmission line theory. From the ratio between the inner voltage and the shield current, a coupling resistance can be calculated.
