How much kW power consumption can a 1000 kVA transformer withstand?

There is an old-fashioned 1000 kVA transformer with an existing load of about 200kW. If a new load of about 600kW is to be added, can this transformer bear it?

The capacity unit of the transformer is kVA, and the power unit of the electrical equipment is kW. The difference between the two is that when calculating the power kW of the equipment, the power factor needs to be multiplied. That is to say, the transformer with a capacity of 1000 kVA transformer can only be used when the power factor is 1. It will be able to output a power of 1000kW at full load, but it is basically impossible in practical applications.

When designing, if we compensate the power factor to 0.95 through power compensation, then the active power output by the transformer should be: 1000×0.95=950kW.

Note: The power company requires that the power factor must be above 0.9, otherwise there will be penalties; but the power factor cannot exceed 1, otherwise the system voltage will increase and affect the normal operation of the system.

The 1000 kVA transformer originally supplied power to 200kW electrical equipment, and now 600kW electrical equipment has been added. The total active power of the electrical equipment has reached 800kW, which still does not exceed the calculated value.

Therefore, a 1000 kVA transformer originally supplied power to 200kW electrical equipment, and now a 600kW electrical equipment is added. As long as we can increase the power factor to the required value, the transformer can run safely for a long time.
