This is illustrated in Fig. , experimental results of breakdown are plotted in pressure vs. elec­ trode area diagram. As can be seen from this figure, conditioning effect is appreciable in regions II and III. Region I is free from conditioning effect since the gap is only governed by the characteri­ stics of the SFfi gas and initiation electrodes. On the other hand, in region IV the gap was free from conditioning effect because the electrode had plenty of radial weak points in comparison with the number of breakdowns in a test.

There have been many publications covering the breakdown in non-uniform fields [15-17], In uniform fields breakdown voltage of SFfi increases linearly with gas pressure. of non-uniform fields, Paschen's law is generally not valid, since / adx is not a function of the product pd. Breakdown voltages normally show an increase with gas pressure, but anomalies arising from space charge effects are observed. 25 mm diameter point anode and a plane cathode and observed that the break­ down voltage increased with gas pressure to a maximum value at a pressure p = 6 bar.

The reasons for the improved performance of coated electrodes are not clear, although Cookson [68] suggested that the resistivity of the film seemed to play an important role in the breakdown mechanism. This dependence of the breakdown voltage on the resistivity has not been clearly established. Investigations carried out [66] using various dielectric coatings, viz. epoxy varnish, paraffin wax, anodized aluminium and polyurethane varnish clearly showed that the breakdown voltage increases substantially when the dielectrics used have a volume resistivity greater than 10 ohm cm.
