EMI measurements of lightning systems
Abstract
Electromagnetic interference (EMI) measurements were made on several types of gas discharge lamps operated at 60 Hz and at high frequency. Electric and magnetic field data were collected to determine the near field impedance (1 to 4 kHz). The radiated E field at one meter from the lamps was 1 to 10 volts per meter. H fields were measured at 1 milliamp per meter. On-site EMI measurements from an installation of 140 solid state ballasts operating lamps at high frequency show radiated and conducted levels that are about the same magnitude as those produced by a single solid state ballasted system.
