From 1985 the experiment triggering the lightning discharge to power transmission line and the protection equipments has been carried out. In the winter or 1985, the experiment of lightning to totalling to 15, including the striking test to ground wire, has been performed successfully. In the winter of 1986, the site of experiment was shifted to the Okushishiku mountain at the altitude of about 1000 meters and the experiment striking the power transmission line of 500KV was successfully performed on 4th of December as the first trial in the world. For the experiment new techniques were developed to trigger lightning fromthe bottom of steel wire trailed by rocket to the tip of arm of transmission tower.In the winter of 1987, the experiment was countinued with eleven successful triggerings, which included four discharges to tower, one discharge to ground wire. and one discharge to phass conductor. It was an important experience to realize the striking to phase conductor by a miss-shielding of ground wire together with the damage of the ground wire by discharge current.Two times of striking test to arresxtors were also perfomed auccessfully with the damage of ZnO elements by the discharge current over a loboratory scale. The discharge currents flowing tower and ground wire, and the voltages induced across the line insulators and between tower root and ground, were measured in the same time with the measurements of the discharge current and electric field at ground together with the accorstic and photograghic records of the discharge.

从1985年开始，对输电线路及保护设备进行了触发雷电放电的实验。 1985年冬天，包括对地线的雷击试验在内，共进行了15次雷击试验，并取得了成功。 1986年冬，试验地点转移到海拔1000米左右的奥石库山，并于12月4日成功进行了500KV输电线路试验，为世界首次试验。试验中采用了新技术，从火箭牵引的钢丝底部触发到输电塔臂尖。1987年冬，试验累计成功触发11次，其中向塔放电4次，向地线放电1次。以及对相导体的一次放电。实现地线误屏蔽对相导体的打击以及放电电流对地线的损坏是一次重要的经验。还成功地进行了两次避雷器的打击试验，放电电流对ZnO元件的损坏达到了实验室规模。测量流过杆塔和地线的放电电流、线路绝缘子两端以及杆塔根部和地面之间感应的电压，同时测量放电电流和地面电场，并记录放电的照相记录。
