network_cof_transformers {CNAIM}

Network cost of Failure for Transformers

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_transformers(tf_asset_category, actual_load_mva, secure = T)

Arguments

tf_asset_category

String The type of Transformer asset category Options: tf_asset_category = c("6.6/11kV Transformer (GM)", "20kV Transformer (GM)", "33kV Transformer (GM)", "66kV Transformer (GM) " "132kV Transformer (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.
