DIAGNOSTICS OF TRANSFORMER COMBINED WITH THERMOVISION

Abstract

Power transformers are key equipment for transfer and distribution of the electric power. Considering the significance of the power transformers in the electric sys-tem, their price and possible damages occurred by acci-dents, it is necessary to pay attention to their higher preven-tion. To prevent failure states of transformers, we perform different types of measurements. They shall illustrate a mo-mentary state of the measured equipment and if necessary to draw attention in advance to changes of parameters, which have specific relationship to no-failure operation of the equipment.
