Generally, the discharge electrode used in the large scale electrostatic precipitator (EP) is long elastic wire. The self-sustained vibration would be given rise to on such an electrode by electrostatic force due to the corona discharge. Although it is well known that the vibration of discharge electrode induces fatigue of material and depresses its precipitating function, the mechainsm of this particular vibration seems not to have been extensively studied. In order to clarify a mechanism of the vibration, we investigated a generation process of the negative damping force acting on the vibrational electrode by detecting a phase difference between the ripple of corona current having the same as vibration frequency and the vibrational displacement of the discharge electrode. The experimental results indicate that the ripple of corona current take place in 1&acd
