This paper describes the electrical characteristics of the polymer lightning arresters(L.As) used to protect distribution lines and power facilities from surge. For the relative comparison, the characteristics assessment was done for 2 states of L.As before and after water immersion treatment. The L.As for the comparative test were immerged with water of 95[℃] considered a severe condition. After the immersion treatment, the assessment was carried out for material analyses in chemical structure(FTIR : fourier transform infrared spectrophotometer). Electrical performance measured insulation resistance measurement, leakage current measurement, critical operation voltage measurement etc.. In addition to, the results were compared with those for the L.As deteriorated in the field. Thus, the accelerative deterioration degree of polymer materials by immersion treatment was evaluated, by which the structural defects of the polymer L.As could be inferred.

Three types of Point of Use (POU) gas abatement equipments for PFCs were demonstrated in this paper. Their main parts and gas treatment mechanisms were well introduced. In addition, abatement efficiencies related to PFCs for each other were tested and compared. Results show that heat-wet type scrubbers have removal efficiency about 95% for NF3. Burn-wet and arc plasma type scrubbers exhibit about 95-96% removal efficiency for CF4 and 97-96% for SF6 gas treatment.
