pof_future_ohl_fittings_50kv: Future Probability of Failure for 50 kV Fittings

In CNAIM: Common Network Asset Indices Methodology (CNAIM)

Future Probability of Failure for 50 kV Fittings

Description

This function calculates the future annual probability of failure per kilometer for a 50 kV fittings. The function is a cubic curve that is based on the first three terms of the Taylor series for an exponential function.

Usage

pof_future_ohl_fittings_50kv(
  placement = "Default",
  altitude_m = "Default",
  distance_from_coast_km = "Default",
  corrosion_category_index = "Default",
  age,
  measured_condition_inputs,
  observed_condition_inputs,
  reliability_factor = "Default",
  k_value = 0.0096,
  c_value = 1.087,
  normal_expected_life = 40,
  simulation_end_year = 100
)

Arguments

placement	String. Specify if the asset is located outdoor or indoor.
altitude_m	Numeric. Specify the altitude location for the asset measured in meters from sea level.altitude_m is used to derive the altitude factor. See page 111, table 23 in CNAIM (2021). A setting of "Default" will set the altitude factor to 1 independent of asset_type.
distance_from_coast_km	Numeric. Specify the distance from the coast measured in kilometers. distance_from_coast_km is used to derive the distance from coast factor See page 110, table 22 in CNAIM (2021). A setting of "Default" will set the distance from coast factor to 1 independent of asset_type.
corrosion_category_index	Integer. Specify the corrosion index category, 1-5.
age	Numeric. The current age in years of the conductor.
measured_condition_inputs	Named list observed_conditions_input
observed_condition_inputs	Named list observed_conditions_input conductor_samp = c("Low","Medium/Normal","High","Default"). See page 161, table 199 and 201 in CNAIM (2021).
reliability_factor	Numeric. reliability_factor shall have a value between 0.6 and 1.5. A setting of "Default" sets the reliability_factor to 1. See section 6.14 on page 73 in CNAIM (2021).
k_value	Numeric. k_value = 0.0069 by default. This number is given in a percentage. The default value is accordingly to the CNAIM standard on p. 110.
c_value	Numeric. c_value = 1.087 by default. The default value is accordingly to the CNAIM standard see page 110
normal_expected_life	Numeric. normal_expected_life = 60 by default. The default value is accordingly to the CNAIM standard on page 107.
simulation_end_year	Numeric. The last year of simulating probability of failure. Default is 100.code

Value

DataFrame. Future probability of failure along with future health score
