Assessment of IR SF6 Insulated Equipment

Assessment of IR SF6 Insulated Equipment

Power arc behaviour in gas insulated equipment and the influence of arc motion on damage resulting from simulated faults were investigated in the laboratory. Experiments were carried out with power-frequency currents up to 22 kA in a co-axial test chamber insulated with pressurized SF6 and air. Arc motion was measured with time-of-flight and infrared thermal imagery techniques for various ...
