Measurements and Analysis of 115KV Power Line Noise and its Effect on Pueblo Test Site Radio Links,

摘要

Noise measurements were made for 115KV power lines near the frequencies 166, 217and 406.8MHz with a receiver bandwidth of 1MHz. The measurements consisted of counting the numbers of pulses per minute at preset threshold values and RMS. The variations of the noise level vs the lateral distance from the power line were also measured. The worst noise level, -40 dBm,was observed at 217MHz under a noisy power line. The results of these measurements show that,under normal conditions,power line noise will not have significant effects on the radio links at the Pueblo Test Site.
