pof_future_switchgear_30_60kv: 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
)

Value

Numeric. Current probability of failure per annum.

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.
