environmental_cof_transformers {CNAIM}

Environmental cost of Failure for Transformers

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_transformers(
  tf_asset_category,
  prox_water,
  bunded,
  size_kva_mva = NULL,
  size_conversion = NULL
)

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) ").

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.

size_kva_mva

Numeric The MVA KVA rating for the transformer

size_conversion

String The size conversion for the transformer
