FIELD: power engineering.
SUBSTANCE: invention relates to the field of electric power engineering and is intended for continuous monitoring of the technical condition of power oil-filled transformers. Substance: the system is additionally equipped with an integrated sensor unit 5 including an oil-dissolved gas concentration sensor 6, a solid insulation humidity sensor 7, and a mechanical impurity concentration sensor 8. The oil input and output of the integrated sensor unit 5 are connected to the oil input and output of the thermosyphon filter 12 of the power transformer, respectively. The information output of the integrated sensor unit 5 is connected with the second input of the measuring and converting unit 2.
EFFECT: increase in the reliability of monitoring the technical condition of a power oil-filled transformer by early detection of occurring faults therein.
