This function calculates the oil test modifier for 33/10kV, 66/10kV and 132kV transformers and tapchangers. See e.g. section 6.11 on page 64 in CNAIM (2017).

Usage

oil_test_modifier(
  moisture = "Default",
  acidity = "Default",
  bd_strength = "Default"
)

Arguments

moisture

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

acidity

Numeric. Refers to the acidity level in the transformer oil. Acidity levels are measured in (mgKOH/g). A setting of "Default" will result in the best possible result.

bd_strength

Numeric. Refers to the breakdown strength. Breakdown strength is measured in kV. A setting of "Default" will result in the best possible result.

Value

Data table.
