Abstract

The paper analyses passive interference on radio station from the +800kV UHV power transmission lines because of electromagnetic scattering on the UHV power transmission lines, overhead ground and iron tower caused by external electromagnetic field, with the moment method NEC programming based on wire antenna calculation theory. The conclusion has been obtained that passive interference on radio station is around 1dBmuV/m in 1MHz-30MHz and tabling the passive interference protecting distance proposes.
