environmental_cof_ehv_cables {CNAIM}

Environmental cost of Failure for EHV UG cables & 132 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

Usage

environmental_cof_ehv_cables(ehv_asset_category, prox_water, bunded)

Arguments

ehv_asset_category

String The type of EHV cable distribution asset category Options: ehv_asset_category = c("33kV UG Cable (Oil)", "33kV UG Cable (Gas)", "33kV UG Cable (Non Pressurised)", "66kV UG Cable (Oil)", "66kV UG Cable (Gas)", "66kV UG Cable (Non Pressurised)", "132kV UG Cable (Oil)", "132kV UG Cable (Gas)", "132kV UG Cable (Non Pressurised)").

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.
