How many amps is a 25 KVA 3 phase transformer?
Three Phase Transformer
| KVA | 208V | 600V |
|---|---|---|
| 20 | 56.6 | 19.3 |
| 25 | 69.5 | 24.1 |
| 30 | 83.4 | 28.9 |
| 37.5 | 104 | 36.1 |
What is the full load current in the secondary?
The full load current I(A) in amps is equal to 1000 times of transformer rating S(kVA) in kVA divided by the multiplication of root 3 times of line to line voltage V(V) in volts. V(S-V) = Secondary voltage in volts.
How do you calculate secondary current?
The secondary current is equal to the product of the primary voltage and primary current divided by secondary voltage.
How to calculate the full load current of a transformer?
Three Phase 600V Class To calculate full load current, use this formula:To calculate KVA, use this formula: Amps = KVA ÷ Volts ÷ 1.732 x 1000KVA = Volts x Amps x 1.732 ÷ 1000 Fields containing ” – ” indicate the current value exceeds the capacity of some current-carrying components such as bushings, cables, bussing, etc.
What are the amps of a single phase transformer?
Single Phase Transformer Full-Load Current (Amps)= kVA × 1000 / V Three Phase Transformer Full-Load Current (Amps) = kVA × 1000 / (1.732 × V)
How to calculate primary and secondary voltage in a transformer?
V(primary) = V(secondary) * I(Primary) / I(secondary) The secondary voltage is equal to the product of the primary voltage and primary current divided by secondary current. V(secondary) = V(primary) * I(Primary) / I(secondary) The primary current is equal to the product of the secondary voltage and secondary current divided by primary current.
How to calculate the KVA of a transformer?
The load voltage and load amps must be known to calculate KVA rating. * NOTE: We do not recommend loading a transformer above 80% of its KVA rating. When the KVA rating has been calculated, divide that number by 0.8 to get the minimum KVA rating needed. All values should be reviewed and confirmed by an electrician or electrical engineer.
