safety_cof_ehv_switchgear {CNAIM}

Safety cost of Failure for EHV swicthgear & 132kV CB

Description

This function calculates safety consequences of failure (cf. section 7.3, page 79, CNAIM, 2021). Safety consequences of failure is used in the derivation of consequences of failure see cof().

Usage

safety_cof_ehv_switchgear(ehv_asset_category, location_risk, type_risk)

Arguments

ehv_asset_category

String The type of EHV swicthgear & 132kV CB Options: ehv_asset_category = c( "33kV CB (Air Insulated Busbars)(ID)(GM)", "33kV CB (Air Insulated Busbars)(OD)(GM)", "33kV CB (Gas Insulated Busbars)(ID)(GM)", "33kV CB (Gas Insulated Busbars)(OD)(GM)", "33kV RMU", "33kV Switch (GM)", "66kV CB (Air Insulated Busbars)(ID)(GM)", "66kV CB (Air Insulated Busbars)(OD)(GM)", "66kV CB (Gas Insulated Busbars)(ID)(GM)", "66kV CB (Gas Insulated Busbars)(OD)(GM)")

location_risk

String Type Financial factor criteria for EHV swicthgear & 132kV CB (cf. section D1.2.1, page 178, CNAIM, 2021). Options: location_risk = c("Low", "Medium", "High"). The default setting is location_risk = "Medium".
