environmental_cof_cables_60_30kv {CNAIM}

Environmental cost of Failure for 30-60 kV UG cables

Description

This function calculates environmental consequences of failure (cf. section 7.3, page 79, CNAIM, 2021). Environmental consequences of failure is used in the derivation of consequences of failure see cof().#' @return Numeric. Financial consequences of failure for LV switchgear 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

environmental_cof_cables_60_30kv(ehv_asset_category, prox_water, bunded)

Arguments

ehv_asset_category

Asset category for the analysis

prox_water

Numeric. Specify the proximity to a water course in meters. A setting of "Default" will result in a proximity factor of 1. Thus assume the proximity to a water course is between 80m and 120m (cf. table 231, page 188, CNAIM, 2021).

bunded

String. Options: bunded = c("Yes", "No", "Default"). A setting of "Default" will result in a bunding factor of 1.
