It is due the valve of lightning strike density in Indonesia high enough, and a relatively low level of isolation impuls resistance. The outrate of lightning strikes on the channel very dependent on the height of the pole, the higher the pole the higher the stroke. And also on this channels the use ground wire introduced shielding factors (FP) defined as a result of the induced voltage with ground wire and induced voltage without ground wire. The purpose of this study in know the amount of disturbance caused by the lightning strike which occurs on the channel with ground wire as it protector. From the calculation of the disturbance caused by direct lightning strike on the ground wire is 0.589 disturbances per year and the disturbance caused by induction stroke is 0159 annoyances per year. Thus the total of disturbances due to lightning strikes is 0.419 annoyances per year. So the probability of a 1 year annoyance is 2.38 interference. To direct the channel completely on ground wire, then it can be mentioned that equipment on the LAA channel protected from direct lightning strikes.} }
