Samenvatting
Small capacitive current interruption with air-break disconnectors in a high-voltage network is an interactive event between circuit and arc with multiple re-ignitions during opening.
In order to investigate the transient phenomena, a set-up to measure arc characteristics is
developed and a series of interruption tests is performed. The system voltage is up to 150kV rms and the interruption capacitive current is up to 0.35A rms. The voltages across load- and sourceside capacitances and the current through the disconnector are recorded. Based on test data, arc characteristics such as arc conductance, arc power and v-i characteristic are studied. A comparison between the test and simulation shows good agreement.
