Duty Factor for all cables (incl. submarine cables).

Description

This function calculates the duty factor for under all types of cables depending on the maximum percentage utilisation under normal operating conditions. The duty factor is used in the deriviation of the expected life of an asset. See e.g. expected_life(). For more general information about the derivation of the duty factor see section 6.6 on page 51 in CNAIM (2021)

Usage

duty_factor_cables(
  utilisation_pct = "Default",
  operating_voltage_pct = "Default",
  voltage_level = "EHV"
)

Arguments

utilisation_pct

Numeric. The max percentage of utilisation under normal operating conditions.

operating_voltage_pct

Numeric. The ratio in percent of operating/design voltage.

voltage_level

String. Specify the voltage level. Options: voltage_level = c("EHV", "HV"). Choose "EHV" for cables >= 33kV and "HV" for cables < 33kV .

Value

Numeric. Duty factor for cables.
