Abstract
The disclosure relates to a system for preventing gas bubbles in oil flow to enter a high-voltage device, which system is located in flow direction of the oil before the high-voltage device and comprises a gravitational gas bubble filter in which velocity of the oil flow is decreased by an enlargement of space for the oil flow and in which the gas bubbles in the oil are separated from the oil flow based on the effect of gravity. The invention also relates to a method for preventing gas bubbles in oil flow to enter a high-voltage device, in which method velocity of the oil flow is decreased by an enlargement of space for the oil flow and the gas bubbles of the oil flow are separated from the oil flow based on the effect of gravity.
