Settings OilQ
Via the tab “Settings OilQ” the oil specific parameters can be modified.
By clicking on the oil selector different defined oil types can be chosen to estimate the
breakdown voltage and humidity for this specific oil (see fig. 14).
The limit values of the temperature compensated values of loss factor tan

TC
, humidity
and breakdown voltage can be set individually. Please note that this feature will be
available after the temperature compensation has been initialized properly as
described on the page 20. These limit values can vary on the different country
standards depending on your localization. Please refer to your local standards.
The oil parameters (= coefficients) can be modified manually by clicking on the Button
“Change Oil Parameters”. A new window will open (see fig. 15,16):
- the name of the oil can be changed in the first line.
- a0 and b0 are the coefficients of the linear fit of a multiple point calibration
(minimum number of point = 2) to estimate the humidity.
- c0, d0, e0, f0 are the coefficients of the second order equation to estimate the
breakdown voltage.
