The insulator dimensioning is based on field records on the "highest leakage current peaks" (Ih) of test insulators, but in a reduced scale: shorter insulators, lo wer voltage stress. The proposed design procedure is theoretically justified using a well known mathemati cal model for partial f lashover on a nolluted insuli tor under alternating voltage. Statistical variati-ons of the narameters of this model are taken into account. The nrinciples of risk-of-failure calculation are developed. The aim is to allow a more efficient use of available exnerimental information and to design a simpler, easier to run and cheaper field test station for collecting relevand data on insula tor performance in a polluting environment. A test station and a specially designed collecting and arocessing system for the test data, which suit the needs of the proposed design method, are also presented. Microprocessor technology has been used for improved accuracy, reliability and flexibility. Preliminary results are commented.
