Full title and description

Limits of electromagnetic interference from overhead a.c. powerlines and high voltage equipment installations in the frequency range 0.15 MHz to 3000 MHz (AS 2344:2016). This standard establishes emission limits and measurement/compliance requirements for radio disturbance produced by alternating-current overhead powerlines and associated high-voltage (HV) equipment installations.

Abstract

AS 2344:2016 specifies radiated and conducted electromagnetic emission limits for a.c. overhead powerlines and high-voltage equipment in the 0.15 MHz to 3000 MHz band, defines measuring apparatus and test methods, and gives compliance procedures (preferred and alternative methods) to protect broadcast and other radio communications services.

Scope

AS 2344:2016 establishes limits for electromagnetic interference (radio disturbance) from a.c. overhead powerlines and high-voltage equipment installations across 0.15 MHz to 3000 MHz. Limits are specified with reference to geographic zones and coverage areas (Region 3, Zones A/B/C) and are intended to protect broadcast reception and other radio communications including navigation and safety-of-life services. The standard describes measurement apparatus, test methods, preferred compliance procedures (the 80/80 rule) and an alternative method with weather and seasonal correction considerations. The limits assume defined corridors/boundaries around powerline installations where reception cannot be guaranteed; outside those corridors satisfactory reception is expected as defined by ITU criteria.

Key topics and requirements

• Frequency range covered: 0.15 MHz to 3000 MHz (radio disturbance limits across VLF/LF/MF/HF/VHF/UHF up to 3 GHz).
• Emission limits specified by geographic zones/coverage areas (Region 3 — Zones A, B, C).
• Defined measuring apparatus and measurement uncertainty requirements (reference to CISPR/ITU measurement practice).
• Test methods and procedures for on-site measurements, including handling of background noise and site conditions.
• Compliance criteria: preferred 80/80 rule and an alternative method with application notes on weather and seasonal corrections.
• Appendices providing tabulated limits and guidance for frequency sub-ranges (below 30 MHz, 30 MHz–1 GHz, 1 GHz–3 GHz).

Typical use and users

Used by power utilities, transmission system operators, HV equipment manufacturers, RF and EMC consultants, regulatory authorities, broadcast and telecommunications planners, and test laboratories for planning, impact assessment, compliance testing and mitigation of radio disturbance from overhead power infrastructure.
