Ring Wave Generator
RWG61000-12 Ring Wave Generator is the test equipment in conformity to IEC (the International Electrotechnical Commission) standard IEC 61000-4-12 and ANSI-C62-41. This instrument is used for the simulative electrical network, the power supply of the reactive load and the control line switch, as well as sensing the ring wave of the low voltage cables terminal equipment caused by the disconnection of the power circuit, fault and insulation breakdown or lightning stroke.Specifications:1.Main technical parameters• Voltage rising time (the first peak): 0.5μs±20% (open circuit state)• Current rising time (the first peak): ≤1μs(short circuit state)• Oscillation frequency: 100kHz±10% • Attenuation (for each peak): the second peak value is 40%~80% of the first peak value, the third peak value is 40%~80% of the second peak value,the forth peak value is 40%~80% of the third peak value, the most ideal attenuation ratio is that the next peak value is 60% of the prior peak value• Recurrence:1~60 transient states per minute• Output impedance: 12Ω and 50Ω±20% (switchable)• Open circuit peak voltage: 0.20kV(-10%)~6.0kV(+10%)• Short circuit current (minimum peak):When the output impedance is 12Ω, the short circuit current is 500A; when the output impedance is 50Ω, the short circuit current is 120A• The phase relation with the supply frequency: (0°~360°,10°stepping)• The polarity of the first semi-circle: positive or negative can switch over• Pulse frequency:1~999 times• RWG61000-12 has already combined with a coupling/decoupling network which is 3-phases/5-wires and output 380V/16A max for EUT2.Output voltage waveform definitionOscillation frequency of the open-circuit voltage (1/T):100KHz±10% Applicable standards: IEC61000-4-12:2006 Open-circuit output voltage(PK1): (200V~4000V)±10% Open-circuit voltage waveform frontier(T1): 0.5μs±20% at (10%~90%)PK1Open-circuit voltage wave attenuation rate: 0.4<(PK2)/(PK1)<0.80.4<(PK3)/(PK2)<0.80.4<(PK4)/(PK3)<0.83.Short-circuit current wave frontier(T2): 10%~90% P1≤1μs
