Air Gap Testing Using Trailing Wire Antenna (TWA) Waveform

摘要

Results of tests of various electrode geometries subjected to high voltage electrical discharge are reported along with test conduct. Three geometries (point-plane, rod-plane, and rod-rod) were tested with both positive and negative voltages. The effect of a uniform field on breakdown voltage was also investigated. The data obtained were compared to the standard lightning breakdown data. The data corresponded well (i.e., within 10 percent) with all other data for negative voltages. Thus, the AWRE voltage holdoff formula is a reasonable method for determining negative voltage breakdown.
