Optical Investigations on Plasma Temperature Estimation in a Model Spark Gap for Surge Currents
Keywords:arc, temperature, plasma, spark gap, surge current, surge protective device
AbstractIn this experimental investigation optical emission spectroscopy is used to characterize the radiation of the plasma in a spark gap during surge. Diﬀerent approaches are used, compared and discussed in order to estimate plasma temperatures. The measurements were carried out in a narrow gap arrangement based on spark gap technology. This model is tested using 8/20 µs surge currents according to the IEC 62475 with amplitudes of 5 kA and 11 kA.
