Power Line Noise Reduction Technique with a Remote Reference

다국어 초록 (Multilingual Abstract)

At Cataract Creek, situated about 15 km north of Wollongong, NSW Australia, a small transient electromagnetic (TEM) profile anomaly over conductive cindered coal is totally obscured by 50 Hz noise measured at stations near power lines. A remote noise prediction filter (RNPF) based on simple scaling and phase correction of the remote noise to match the local noise was tested. A profile anomaly obscured by 50 Hz noise can be recovered with the application of this filter. The remote reference filter is not affected by changes of noise frequency or amplitude, since the changes are monitored by simultaneous measurements at the remote receiver and can be allowed for during the noise filtering process.
