In a delta suppressor capacitors are connected between the live neutral & earth terminals. As the frequency of the R.F.I. rises the impedance of these capacitors falls thus attenuating the R.F.I. at the mains terminal. It can be used for radio suppression of small electric motors & domestic appliances. Connect as close as possible to the source of interference.
