1500 KVA LOAD BANK, P/N 9371L
Calculation of Inductance:
-
- Input Voltage = 4160 VAC L-L
- Power rating: 1500 KVA
- Therefore each coil will be rated for 500 KVA
- Continuous current = 500 KVA / 4160 VAC = 120 Amps
- R = V / I = 4160 VAC / 120 Amps = 34.67 Ohms
- R = 2 x π x F x L
- L = R / (2 x π x F) = 34.67 / (2 x 3.142 x 60) = 92 mH
- Four 23 mH, 120 Amp inductors will be connected in series to get 92 mH, 120 Amps
Notes:
A. Our proposed bus bars are 1″ x 1/4” thick
B. Our proposed enclosure is 50″H x 65″W x 36″D.
C. Our proposed load bank is 12 inductors (each inductor is 23 mH)
D. Our enclosure can be moved with a forklift
E. Three fans are provided for forced air cooling (blowing down)
The customer application is shown below. Twelve each 23 mH, 120 Amp Inductors will be connected in a Delta fashion to offer a 1500 KVAR Load Bank.
The details of the 23 MH, 120 Amp Inductor are shown below:
