Pambuka
The11 Transformer KVminangka salah sawijining transformer medium-voltase sing akeh digunakake ing sistem listrik listrik.
Nalika insinyur utawa para panuku nyebutake11 kVTransformerrating, biasane prihatin karo voltase input (11,000 volt), voltase output, lan kapasitas tenaga (ing kva utawa mva).
Apa tegese "11 KV Transformer Rating?
The11 kVin transformer rating refers to theUtusan (input)voltagethe transformer is designed to handle. This is amedium-voltage level, asring digunakake ing sistem distribusi regional utawa lokal.
Rating Transformer Khas Khusus kalebu:
- Primary Voltage: 11 kV (i.e., 11,000 volts)
- Secondary Voltage: 400 v / 415 v / 690 V, gumantung saka panggunaan
- Power Capacity: Kisaran saka 25 kVA nganti 2500 kva utawa luwih
- Frekuensi: 50hz / 60hz
