This is a report on some experimental results of electric discharge phenomenon observed between crossed cylinders erected with three same electrodes in diameter (1.50 cm., 2.19 cm., 2.73 cm., 3.43 cm.): the upper electrodes are made up of two parallel cylinders impressed with high voltage and the lower single cylinder is earthed.　Positive standard impulse voltage (1.27 X 43.5 μS) and A.C. Voltage (50 Hz) are used as the impressed high voltage. This study is as to the case of experiment in the atmospheric test room.　1. The values of flashover voltage in those experiments need not be corrected by the change of humidity.　2. In the correction by the change of relative air-density (RAD)^, 1.0 suffices the value of o.n in those experiments (RAD = 0.95-1.05).　3. In the impulse voltage test, each of the flashover characteristic curves of the crossed cylinders is divided into three parts by the gap length between the upper and the lower electrodes, while in the A.C. voltage test the curves are divided into two parts.　4. An electrode diameter and a distance between the two high voltage electrodes are main factors which vary the value of the flashover voltage in those experiments.　5. In the impulse high voltage test, if gap length is 70 cm. and over, the flashover characteristic curve is nearly equal to that of the standard rod gap.　6. In those experiments (when gap length is within about 100cm) the air breakdown strength in 50 % impulse flashover test shows maximum distance value in case a distance between the two high voltage electrodes is about three times as long as that of each electrode diameter.　7. In those experiments (when gap length is within about 10cm) the air breakdown strength in A.C. flashover test shows maximum value in case a distance between the two high voltage electrodes is about ten times as long as that of each electro dediameter.
