  • A Study of the Critical Pressure in SF6/N2 Mixtures for

    Abstract: A dual photomultiplier system and a field probe have been used to study the optoelectrical phenomena in commercially pure SF6 and mixtures of SF6 with oxygen-free N2, under impulse voltages in a point-plane gap. The critical pressure has been estimated using an extrapolation technique, and the results have been compared with those of other recently published work.

  • The Effect of Pressure and Gap Distance to AC Breakdown

    The gas mixture ratio was fixed to 10/90, while the total gas pressure was varied between 0.11 MPa to 0.15 MPa with 0.01 MPa intervals. Meanwhile, R6-Plane electrode configuration was used to produce a non-uniform field where the electrodes gap distance was varied between 5 mm to 30 mm. The results show that the breakdown voltage of SF 6 /N 2 (10/90) gas mixtures increases linearly with the increase of gas pressure and electrodes gap distance.
