How many motors horsepower can we operate on a 25 kva transformer?
A 25kVA transformer can withstand a permanent current of 36A 400Vac. So on the paper a 25kVA transformer can supply two 10HP pump with 15\% margin.
How much load can a 25 kva transformer handle?
Three Phase Transformer
| KVA | 208V | 2400V |
|---|---|---|
| 20 | 56.6 | 4.82 |
| 25 | 69.5 | 6.02 |
| 30 | 83.4 | 7.23 |

How do you size a transformer for a 3 phase motor?
Primary Current (current on High Voltage side) is 5.25 amps. KVA = (√3. V x I) /1000= (1.732 × 11000 × 5.25)/1000=100 KVA….Transformer selection is based on mainly 4 parameters:
- Power rating in KVA (Kilo Volt Amperes),
- Primary voltage,
- Secondary voltage,
- Tap arrangement.

How to calculate the amperage of a three phase transformer?
Three-phase Transformer Amps = Transformer kVA rating * 1000 / (E*1.73) Find the amperage rating of a transformer having 225 kVA and 500 V in case of single and three phase
How to find the amperage rating of a transformer having 225 kVA?
Find the amperage rating of a transformer having 225 kVA and 500 V in case of single and three phase In the case of single-phase: I = 225 * 1000 / 3.3kV = 68.18 Amps In case of three-phase: I = 225 * 1000 / (230 * 1.73) = 39.41 Amps 500 kVA, 3.3 kV Transformer Amps
How many amps does a 500 kVA transformer produce?
500 kVA, 3.3 kV Transformer Amps. 500 kVA Single Phase Transformer: I = 500 * 1000 / 3.3kV = 151.5 Amps. 500 kVA Three phase Transformer: I = 500 * 1000 / (3.3 * 1.73 kV) = 87.58 Amps.
