This Standard establishes limits for electromagnetic interference (radio disturbance) from alternating current (a.c.) overhead powerlines and high voltage (HV) equipment installations in the frequency range 0.15 MHz to 3000 MHz. The limits are specified in accordance with geographical zones and coverage areas. Australia is situated in Region 3 and the various coverage areas within Zones A, B and C of Region 3 are shown in Figure 1.These limits are specified for the protection of broadcast radio reception and other radio communication services, including navigation and safety-of-life services.
