The Spectrum Analyzer Applied to the Measurement of EHV Power Line Radio Noise

In order to reduce time and improve the quality of measurements* of EHV power line radio noise, the use of spectrum analyzers and X-Y recording techniques with radio noise meters was investigated. Comparisons were made with the usual manual readings taken simultaneously from radio noise meters used as the standard measuring instruments. With the spectrum analyzer, measurements of radio noise from conductor corona both in rain and fair weather conditions were made in the 1 MHz frequency region. In addition, the interference from a gap-type source was successfully measured over a frequency range from 10 kHz to 1 GHz.
