FIELD: electric power engineering.
SUBSTANCE: according to the invention, the substation has cabin 16. On ODU 1 there are transformers 2, one side of windings of which are connected to star, which is combined and connected to earthing 9 through metal resistor 8. Novelty is that resistor 8 is installed on insulators 10 in pipe 11, at one end of which there is electric fan 12 controlled by power supply unit 13. Actuator 14 switches to two directions damper 17, which switches air flow into two directions: outside (flask 15) or inside cabin 16 (flared end 14). Controller 22 according to readings of sensors 19-21 controls the speed of electric fan 12 and damper, allowing to use for heating heat released in resistor 8, caused by flow of current corona power line 6 and geomagnetic current.
EFFECT: technical result consists in improvement of efficiency of substation.
