Abstract
The paper presents results of a survey of transient recovery voltage (TRV) on the CEGB 400 kV system, made by a series of digital-computer calculations, to provide a basis for the preparation of TRV parameters for a revised switchgear purcinising specification. The results are obtained for 3-phase earthed fault and single-phase-to-earth fault conditions. Details of the system represented in the survey are given, together with the method of representation and analysis of results. The relationship between fault current and rate of rise of TRV is discussed, and factors affecting peak voltage are considered
