8. Ring Wave
The ring wave is a typical oscillatory transient, induced in low-voltage cables due to the switching of electrical
networks and reactive loads, faults and insulation breakdown of power supply circuits or lightning.
The phenomena are simulated by a damped oscillatory transient with defined 0,5

s rise time and 100 kHz
oscillation frequency.
Voltage rise time T1:
0,5

s ± 30 %
(open-circuit condition)
Current rise time T1: 0.2 to 1.0

s
(short-circuit condition)
Voltage osc. frequency: 100 kHz ±10%
Defined as the reciprocal of the period
between the first and third zero crossings
after the initial peak.
Decaying: 0,4 < Ratio of Pk 2 to Pk 1 < 1,1
0,4 < Ratio of Pk 3 to Pk 2 < 0,8
0,4 < Pk 4 to Pk 3 < 0,8
No requirements for other peaks.
