f_cof_transformer_11kv {CNAIM}

Financial Consequences of Failure for a 6.6/11 kV Transformer

Description

This function calculates financial consequences of failure (cf. section 7.3, page 79, CNAIM, 2021). Financial consequences of failure is used in the derivation of consequences of failure see cof().

Usage

f_cof_transformer_11kv(kva = "Default", type = "Default")

Arguments

kva

Numeric. The rated transformer capacity measured in kVA for a 6.6/11 kV transformer. Rated capacity is used to derive the type financial factor. For a general description of type financial factor see section 7.3.3.1 on page 80 in CNAIM (2021). A setting of "Default" will result in a type financial factor equal to 1 (cf. section D1.2.1, page 178, CNAIM, 2021).

type

String. Relates to the accessibility of the transformer Options: type = c("Type A", "Type B", "Type C", "Default"). A setting of "Type A" - Normal access. A setting of "Type B" - Constrained access or confined working space. A setting of "Type C" - Underground substation. A setting of "Default" - Normal access thus same as "Type A" setting (cf. table 221, page 180, CNAIM, 2021).

Value

Numeric. Financial consequences of failure for a 6.6/11 kV transformer.
