Liftoff of Submillimeter Conducting Particles Under DC Electric Field
Particles in gas insulated systems may affect system operations. This work studies the liftoff of steel particles under the DC electric field. The particle sizes are 181.01 or 106.82 µm. The electrodes are parallel and the gap between electrodes is 1 cm. Ramp and step voltages ranges are 0-12kV. This experiment uses a computer to control voltage supply and image acquisition. The number of particles lifted from the grounded electrode are taken by a camera. The results show the liftoff efficiency of particles. The liftoff efficiency of smaller particles is lower than larger particles for ramp and step voltages. Also, the liftoff efficiency of positive voltage is higher than the negative voltage. The step voltages are more efficient in the liftoff ramp voltage.
