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

open access: yesInternational Journal of Electrical Power and 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
