# How many kilowatts can a 1250kva transformer take?

Even if the 1250KVA power transformer provides all the active power, the KW is only 1250KW. Of course, it is impossible to afford it.
If the equipment is running at the same time, the active power is 3115KW, all are inverters, then the power factor is estimated to be quite low. Assuming 0.8 is good, then at least the transformer needs to have a minimum capacity of 3115/0.8 KVA. Generally, the transformer needs to have a good margin. Degree is about 80%, so if the power factor is 0.8, the transformer efficiency is 80%.
The load of the 1250Kva transformer is 1000 kW. The load of the ,Distribution transformer is generally 0.8 times the capacity of the transformer, 1250 × 0.8 = 1000kw, so the load of the transformer of 1250Kva is 1000 kW.
As a load, the transformer runs smoothly under small load conditions (0.5~0.7) and has good economy. When the load factor of the transformer is between 63% and 67%, the efficiency of the transformer is the highest.
Transformer: A device that uses the principle of electromagnetic induction to change the AC voltage. The main components are the primary coil, the secondary coil, and the iron core (core). The main functions are: voltage conversion, current conversion, impedance transformation, isolation, voltage regulation (magnetic saturation transformer) and so on.
Its rated current = capacity / voltage × 6/10. Load P = √ 3 × line voltage × line current × power factor. The current on the 400V side is about 1800A.
