| Research Abstract |
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.
