The Partial discharge measuring system were constructed for analyzing treeing phenomena. The discharge magnitude and discharge luminescence were measured at same time. The experimental results as follows.(1) The discharge magnitude were proportioned to the luminous quantity.(2) The discharge magnitude and the luminous quantity are the maximum value at phase angle area of phi_7 (40ﾟ) and phi_<17> (220ﾟ).(3) The tree propagation speed was more accelerated by the discharges at phi_7 and phi_<17> system.(4) The discharge magnitude correlate closely the effective instantaneous voltage value multiply dv/dt.(5) The discharge luminescence was observed at void at phi_3, phi_4, phi_5.(6) The discharge path by single discharge were observed at single tree channel or multi tree channels.

为分析树枝状放电现象，建立了局部放电测量系统。同时测量了放电强度和放电发光。实验结果如下。(1)放电强度与发光量成正比。(2)在相位角φ_7（40 °）和φ_（220 °）处放电量和发光量最大<17>。(3)在phi_7和phi_4系统放电更能加快树木的繁殖速度<17>。(4)放电幅值与有效瞬时电压值乘以dv/dt密切相关。(5)在phi_3、phi_4、phi_5的空隙处观察到放电发光。(6)单次放电的放电路径可以在单树通道或多树通道中观察到。
