network_cof_ehv_switchgear {CNAIM}

Network cost of Failure for EHV swicthgear & 132kV CB

Description

This function calculates network cost of failure for all asset categories exclusive the assets EHV and 132kV transformers. (cf. section 7.6, page 87, CNAIM, 2021). Network cost of failure is used in the derivation of consequences of failure see cof().

Usage

network_cof_ehv_switchgear(ehv_asset_category, actual_load_mva, secure = T)

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)")

actual_load_mva

Numeric. The actual load on the asset

secure

Boolean If the asset is in a secure network or not

Value

Numeric. Network cost of failure.
