NZS 6869:2004 PDF Download

The NZS 6869:2004 standard sets forth specific limits and measurement methods for electromagnetic noise generated by high voltage A.C. power systems operating in the frequency range of 0.15 to 1000 MHz. The purpose of this standard is to establish boundaries to prevent electromagnetic interference and radio disturbance caused by overhead power lines and high voltage equipment installations.

These limits are crucial to protect the integrity and reliability of broadcast radio reception as well as other radio communication services such as navigation and safety-of-life services. Compliance with these limits ensures that the electromagnetic noise emitted by high voltage power systems does not disrupt or interfere with the proper functioning of these essential communication services.

The standard also outlines the measurement methods that should be used to assess the electromagnetic noise emitted by these power systems, providing a standardized approach for accurate and consistent measurement across different installations.
