environmental_cof_hv_switchgear_distribution {CNAIM}

Environmental cost of Failure for HV switchgear distribution

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 HV switchgear

Usage

environmental_cof_hv_switchgear_distribution(
  hv_asset_category,
  type_env_factor,
  prox_water,
  bunded
)

Arguments

hv_asset_category

String The type of HV switchgear distribution asset category Options: hv_asset_category = c("6.6/11kV CB (GM) Secondary", "6.6/11kV RMU", "6.6/11kV X-type RMU", "6.6/11kV Switch (GM)", "20kV CB (GM) Secondary", "20kV RMU", "20kV Switch (GM)")

type_env_factor

String The type environment factor of HV asset category Options: type_env_factor = c("Oil", "SF6", "Niether", "Default").

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.
