network_cof_hv_switchgear_primary {CNAIM}

Network cost of Failure for HV Switchgear Primary

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_hv_switchgear_primary(
  hv_asset_category,
  no_customers,
  kva_per_customer = "Default"
)

Arguments

hv_asset_category

String The type of HV asset category Options: hv_asset_category = c("6.6/11kV CB (GM) Primary", "20kV CB (GM) Primary")

no_customers

Numeric. The numner of customers fed by an individual asset.

kva_per_customer

Numeric. If the asset have an exceptionally high demand per customer type in kVA per customer. A setting of "Default" results in a multiplication factor of 1 (cf. table 18, page 90, CNAIM, 2021).

Value

Numeric. Network cost of failure.
