Taking seven units of XP-160 insulator string for example,the DC pollution flashover mechanism of polluted insulator string was researched.

The pollution flashover mechanism was analyzed by utilization of a physical model with connection in series of surface electric arc and residual pollution layer resistances;and the measures for anti-pollution flashover were proposed.

In this paper, the formula and producing process of the glisten glaze are discussed systematically, as well as the crystallization of CeO2 in the glisten glaze and the glistening mechanism.

In this paper the research situation of the flashover mechanism of polluted insulators in recent decades home and abroad, i.

Firstly, the mechanism of flicker disturbance and transfer rule of flicker in power system are discussed in this paper.

Relation between coastal atmospheric quality indices and power equipment pollution flashover;

Effect analysis on application of organic coating RTV in anti-pollution flashover of power devices;

Analysis and countermeasures of 220 kV substation pollution flashover;

In order to seek a method to show definitely the various stages of creeping discharge of contamination insulators and to supply early pre-warning for contamination flashover,the artificially polluted insulators were investigated by the fog chamber method in the laboratory.

The relation of the leakage current between the environment factor and contanmination degree was analysed there exists excellent practical use,to prevent the occurrence of contamination flashover fault,an effective monitoring method was provided.

By means of artificial pollution test the contamination flashover characteristic of composite insulators lost hydrophobicity under DC voltage is researched.
