High-voltage insulators can create partial discharges (corona) due to high electric field stress. These discharges generate electromagnetic noise in the radio frequency spectrum (typically 0.15 MHz to 30 MHz). This noise can interfere with: These discharges generate electromagnetic noise in the radio
: Tests are typically conducted at 0.5 MHz or 1.0 MHz . The standard allows for alternative frequencies between 0.5 MHz and 2.0 MHz if agreed upon by the purchaser and manufacturer.
The test environment must be shielded from external radio stations and ambient noise to ensure accurate results.
