Abstract

The present invention relates to a method for determining temperature information, or information related to temperature information, related to a static electric induction device assembly (10). The static electric induction device assembly (10) having a vertical extension in a vertical direction (z). The method comprises performing the following for at least a static electric induction device portion (20): - determining a heat loss value (Q), indicative of a heat loss for the static electric induction device portion (20), the static electric induction device portion (20) having a vertical static electric induction device portion position (z<port>) in the vertical direction (z); - determining a liquid temperature value (T<liq>(z<port>)), indicative of a temperature of a liquid (16) in the vertical static electric induction device portion position (z<port>), and - determining a temperature (T<port>), or information related to temperature information, of the static electric induction device portion (20) using the liquid pressure difference (Δp), the heat loss value (Q) and the liquid temperature value (T<liq>(z<port>)).
