摘要： An electrical surge arrester (diverter) comprises a shedded porcelain housing (2) having a central cylindrical bore within which there is accommodated a series-connected array of non-linear voltage-dependent resistors and spark gaps (Gi). A resistive metal oxide glaze (1) is provided on the internal surface of the bore, and contact fingers (3) extend from components of said array into contact with the resistive glaze at spaced apart locations along the length of the bore. By this means, components of the said array are shunted by a resistor (Ri) constituted by a section of the resistive glaze and these resistors either alone or together with other grading components constitute the grading circuit of the surge arrester for ensuring a reasonably even distribution across the internal components of the arrester of the voltage applied to the arrester.
