Health index and risk assessment models for Gas Insulated Switchgear (GIS) operating under tropical conditions

open access: yesInternational Journal of Electrical Power & Energy Systems, 2020
This article contains the development of the Health Index (HI) and the Risk Assessment (RA) models for Gas Insulated Switchgear (GIS) operating under tropical conditions. A case study of 631 bays of GIS in tropics with service time from 1 up to 30 years is used during the development of the models. The basis for the HI model is the condition assessment
