The ring wave is an oscillatory transient induced in low-voltage cables due to switching of electrical networks and reactive loads, faults, and insulation breakdown of power supply circuits or lighting. The EMC Shop stocks the ring wave generators that produce the waveform per EN/IEC 61000-4-12 immunity test, available for rental or purchase.
