2500KVA transformer rated current 3608A, how much can be overloaded current?
2500kva is the transformer capacity, P is active, COSφ = active / capacity. 0.8 = active / 2500 that active = 2000KW and because of active = 1.732 * UICOSφ and u = 0.4V, COSφ = 0.8 into the equation of current = 3608.5A.
Transformer: Transformer (Transformer) is the use of electromagnetic induction principle to change the AC voltage of the device, the main components are primary coil, secondary coil and core (core). In electrical equipment and wireless circuits, commonly used as lifting voltage, matching impedance, safety isolation and so on. The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage regulator (magnetic saturation transformer) and so on. According to the use can be divided into: distribution transformers, power transformers, sealed transformers, modular transformers, dry-type transformers, oil-immersed transformers, single-phase transformers, electric transformers, rectifier transformers.
Ventilated good circumstances, you can temporarily overload 300A.
