METHOD OF POWER SUPPLY TO CONSUMERS IN CASE OF DAMAGE TO PHASE OF 110 kV ELECTRICAL NETWORK Russian patent published in 2024 - IPC H02J3/20 

FIELD: electrical power engineering.

SUBSTANCE: method of power supply to consumers in case of damage to a phase of a 110 kV electrical network includes installation at the receiving substation as a transformer of a three-phase two-winding transformer with a switch in its neutral; in the event of an accident, relay protection determines the damaged phase and disconnects the network, disconnecting and grounding the damaged phase conductor on both sides using connections between substations, then the transformer neutral is grounded at the receiving end, the voltage level is restored to the full-phase voltage level. After eliminating the cause of damage to the phase conductor, the transformer neutral mode is transferred to ungrounded and the previously damaged phase conductor is turned on.

EFFECT: providing power to consumers in the event of damage to a phase of the 110 kV electrical network before the cause of the accident is eliminated and the transition to normal mode after its elimination.
