IEEE P1897 PDF
This Recommended Practice describes a procedure that electric utility companies and others may use to respond to reports of interference to radio or television reception. It describes procedures to determine if a reported noise is harmful interference to a licensed radio service. It describes modern noise-locating techniques and equipment and protocols that use time-domain noise signatures to investigate and identify radio noise in the field.
This Recommended Practice is intended to help all parties involved in interference reports to understand the best practices used to assess, identify and repair noise problems and have reasonable expectations about the role and responsibilities of each party. It describes ways that utility staff can interact with a complainant to obtain information that will aid the troubleshooting process and it outlines reasonable timelines that will help everyone involved have reasonable expectations about the process and time it can take to respond to, identify, troubleshoot and repair a noise source. The techniques allow a utility to identify which noise sources are actually associated with the reported noise, minimizing troubleshooting and repair costs. The Recommended Practice also allows a utility to determine when reported interference is being caused by a source other than electric utility equipment.
New IEEE Standard – Active – Draft. This Recommended Practice describes procedures that electric utility companies and others may use to address complaints of interference caused by power-line gap noise to radio, television, and other types of wireless communications. It includes discussion on how to determine if a noise may be considered as harmful interference under the FCC rules. Modern noise-locating techniques, equipment and protocols are also described, including the use of time-domain noise signatures (sometimes referred to as signature analysis) to investigate and identify radio noise in the field. These techniques allow an interference investigator to identify which noise source or sources are associated with the reported interference, thus minimizing troubleshooting and repair costs. Troubleshooting and repair recommendations are also included once all the sources have been identified. This Recommended Practice also describes ways to determine and find interference when it is being caused by a source other than electric-utility equipment, such as an electronic consumer device. The methods and techniques contained herein have been validated by decades of usage with positive results by a wide range of users, including but not limited to utilities, professional interference investigators, radio engineers, and even the home hobbyist.
