dga_test_modifier {CNAIM}

DGA Test Modifier

Description

This function calculates the DGA test modifier for 33/10kV, 66/10kV and 132kV transformers. See e.g. section 6.12 on page 65 in CNAIM (2017).

Usage

dga_test_modifier(
  hydrogen = "Default",
  methane = "Default",
  ethylene = "Default",
  ethane = "Default",
  acetylene = "Default",
  hydrogen_pre = "Default",
  methane_pre = "Default",
  ethylene_pre = "Default",
  ethane_pre = "Default",
  acetylene_pre = "Default"
)

Arguments

hydrogen

Numeric. Refers to the hydrogen level in the transformer oil. Hydrogen levels are measured in ppm. A setting of "Default" will result in the best possible result.

methane

Numeric. Refers to the methane level in the transformer oil. Methane levels are measured in ppm. A setting of "Default" will result in the best possible result.

ethylene

Numeric. Refers to the ethylene level in the transformer oil. Ethylene levels are measured in ppm. A setting of "Default" will result in the best possible result.

ethane

Numeric. Refers to the ethane level in the transformer oil. Ethane levels are measured in ppm. A setting of "Default" will result in the best possible result.

acetylene

Numeric. Refers to the acetylene level in the transformer oil. Acetylene levels are measured in ppm. A setting of "Default" will result in the best possible result.

hydrogen_pre

Numeric. Previous results. A setting of "Default" will result in the best possible result.

methane_pre

Numeric. Previous results. A setting of "Default" will result in the best possible result.

ethylene_pre

Numeric. Previous results. A setting of "Default" will result in the best possible result.

ethane_pre

Numeric. Previous results. A setting of "Default" will result in the best possible result.

acetylene_pre

Numeric. Previous results. A setting of "Default" will result in the best possible result.

Value

Data table.
