network_cof_cables_60_30kv {CNAIM}

Network cost of Failure for 30-60 kV UG cables

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(). ehv_asset_category = c("30kV UG Cable (Gas)", "60kV UG Cable (Gas)", "30kV UG Cable (Non Pressurised)", "60kV UG Cable (Non Pressurised)", "30kV UG Cable (Oil)", "60kV UG Cable (Oil)") . The default setting is ehv_asset_category = "60kV UG Cable (Gas)".

Usage

network_cof_cables_60_30kv(ehv_asset_category, actual_load_mva, secure = T)

Arguments

ehv_asset_category

Asset category for the analysis

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.
