pof_future_switchgear_30_60kv: Future Probability of Failure for 30kV and 60kV Switchgear

In CNAIM: Common Network Asset Indices Methodology (CNAIM)

Future Probability of Failure for 30kV and 60kV Switchgear

Description

This function calculates the future annual probability of failure 30kV and 60kV switchgear. 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_switchgear_30_60kv(
  asset_type = "30kV",
  placement = "Default",
  number_of_operations = "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 = "Default",
  c_value = 1.087,
  normal_expected_life = 55,
  simulation_end_year = 100
)

Arguments

asset_type	String Asset Type
placement	String Placement
number_of_operations	String Number of Operations
altitude_m	String Altitude
distance_from_coast_km	String Distance from coast
corrosion_category_index	String Corrosion Category Index
age	Numeric Age
measured_condition_inputs	Named list observed_conditions_input
observed_condition_inputs	Named list observed_conditions_input
reliability_factor	String Reliability Factor
k_value	Numeric. k_value = 0.0077 by default. This number is given in a percentage. The default value is accordingly to the standard "DE-10kV apb kabler CNAIM" on p. 34.
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 = 55 by default. The default value is accordingly to the standard "DE-10kV apb kabler CNAIM" on p. 33.
simulation_end_year	Numeric. The last year of simulating probability of failure. Default is 100.

Value

Numeric. Current probability of failure per annum.
