What Equipment Can 750kva Cast Resin Dry Type Transformer Power?
For a typical 380V industrial power supply, the rated current of a 750kVA transformer is approximately 1145A (I = S / (√3 × U) = 750 / (1.732×0.38) ≈ 1145A).
For motor loads: It is recommended that the total power does not exceed 600kW (a 10% margin is safer for stable operation).
For pure resistive loads such as lighting/heating: It can power a maximum of 700~720kW.
Notes:
- Do Not Operate at Full Load for Long Periods: In actual use, it is advised to run at 80% load (i.e., 480kW) to avoid overheating and extend the transformer’s service life.
- Reactive Power Compensation: If the power factor is lower than 0.8, the actual usable power will be lower (e.g., cosφ=0.7 results in only 525kW). A capacitor compensation cabinet must be installed to improve the power factor.
