power receiving and transforming equipment; substation equipment
Technical term in electrical engineering for equipment that receives high-voltage power and transforms it to a lower voltage, often including switchgear, transformers, and related apparatus. The gloss 'electrical substation' refers to the facility as a whole, while 'transformer' is a key component.
We regularly inspect the factory's power receiving and transforming equipment.
Renovation work on the substation equipment will start next month.
Compound of 受 (receive), 変電 (power transformation), and 設備 (equipment/facilities). A modern technical term with no known historical derivation beyond its component kanji.
