Remote Testing of the UHF Radiation Field Generated by Corona Discharge of the Transmission Lines

Abstract:

The UHF radiation field generated by corona discharge of the two 500kV AC transmission lines was tested. The influencing factors of radiation field, including climate, bundle conductors number and test distance, were analyzed. Test results indicate that the field continuously arranges from 200MHz to 700MHz, mainly from 200MHz to 500MHz. The maximal measurement distance is 300 meters. The climate and bundled conductors number affect the radiation field obviously. The discharge will become intense when the temperature and humidity increase and bundle conductors number decays. The peak values of the electric field strength which decay rapidly with the distance increasing, can arrive several hundreds uV/m. The test results rich the UHF radiation field data and offer references to testing and evaluating the electromagnetic interference generated by corona discharge of ultra-high voltage transmission lines.
