What is the active power of a 1000KVA transformer?

1000 kVA refers to the apparent power of the transformer. Under the rated load of the transformer, if the power factor of the transformer is considered as 0.8, the active power of the transformer is P=1000×0.8=800 kilowatts.

If a load of 1000 kilowatts is carried, the transformer will be overloaded, the temperature of the transformer will rise, the insulation aging will be accelerated, and the service life of the transformer will be reduced.

Under special circumstances, the short-term overload operation of the transformer should not exceed 1/3 of the rated load in winter and 15% in summer.

The limit of the overload operation time depends on the ambient temperature of the transformer and the multiple of the overload.

1000KVA transformers

What is the maximum current of a 1000kva transformer?

Calculated according to the rated current of the transformer

The primary side is approximately 0.058*KVA (transformer capacity, specification 10kV/0.4kV)

The secondary side is approximately 1.44*KVA (transformer capacity, specification 10kV/0.4kV)

1000*1.44=1440A=1000/0.4/√3=1445A

Depends on your S-type transformer, such as S7, 8, 9 transformers can exceed 20%.

Now the transformers from the power supply bureau are S11 and above, which are energy-saving transformers and cannot be overloaded and can only reach 90%.

1000 normal maximum current 1000/1.732/0.38=1520A

Three-phase transformer rated power: S=1.732UI

Knowing S and U, the rated current I can be obtained, which is the maximum current during normal operation.

If it is single phase then: S=UI

If it is a 10KV/0.4KV three-phase transformer, then:

The rated current of the high-voltage side is I1=1000K/1.732/10K=57.74A

The rated current of the low-voltage side is I2=1000K/1.732/0.4K=1443.4A

In addition, the transformer allows short-term overload operation (such as one or two hours), so the actual current of the transformer during operation may exceed over its rated current I.

1000 kva transformer full load current

How to calculate the rated current of 1000kva transformer?

High and low voltage side current calculation, transformer capacity/voltage level/1.732*rated current

Transformer capacity is 1000kVA

High-voltage side current: 1000/10/1.732=57.736A

Low-voltage side current: 1000/0.4/1.732=1443.418A

How to calculate the high-voltage side protection setting of 1000kva transformer?

The transformer capacity is 1000kVA, and the known high-voltage side current of the transformer is 57.736A.

Select the current mutual inductance 100/5, the magnification is 20 times, the calculation method of the secondary side current: 57.736/20=2.8868A.

What is the power factor of a 1000 kva transformer?

A 1000kVA transformer can output 600kW of active power when the power factor cosφ=0.6; but when the power factor cosφ=0.9, it can output 900kW of active power.

If 1 kWh of electricity is 1 yuan, when the power factor is 0.6, the transformer can generate economic benefits of 600 yuan/hour; when the power factor reaches 0.9, the transformer can generate 900 yuan/hour of economic benefits.

What is the no-load loss of a 10 kv dry-type transformer?

SC(B)10-1000KVA/10KV series dry transformer no-load loss standard is 1770W;

SC(B)11-1000KVA/10KV series dry transformer no-load loss standard is 1590W;

What is the no-load loss of a 10 kv oil-immersed transformer?

S11-1000KVA/10KV series oil-immersed transformer no-load loss standard is 1150W;

The no-load loss standard of SH15-1000KVA/10KV amorphous alloy oil-immersed transformer is 450W.

What is the primary variable current of a 1000 kva transformer?

Remember the current value of the high and low voltage sides of a transformer with a common capacity, and linear derivation can be performed for other capacities.

For a 1000KVA transformer, the calculated value of the current on the high-voltage side is 57.73, and the calculated value of the current on the low-voltage side is 1443.42.

Then remember this value, and other capacities can be derived from this. For example, for a 1600KVA transformer, the high-voltage side current is 1600/1000*57.73=92.368A, and the low-voltage side current is 1600/1000*1443.42=2309.472A

How many kilowatts of capacitors need to be configured for 1000Kva transformer reactive power compensation?

It is necessary to know the demand factor of the equipment and the power factor of each equipment to be able to calculate.

If you don’t know it, you can make a rough estimate, generally 45% to 75% of the transformer capacity for compensation.

If you have more inductive equipment, you can use 60~75% to compensate.

How to configure the compensation capacitor for a 1000KVA transformer?

The 1000KVA transformer should be equipped with a compensation capacitor with a capacity of 420kvar.

Factory natural power factor before compensation = 0.8. When the power factor is increased to 0.95 through capacitance compensation, the compensation capacitance is 0.42kvar per 1KW of power, so the capacity of the compensation capacitor that should be configured for a 1000KVA transformer = 1000*0.42=420kvar.

Calculate the reactive power compensation capacity according to the capacity of the transformer:

The efficiency of the transformer is generally 0.8, and the power factor under load is usually around 0.7. When the power factor increases from 0.7 to 0.95, the reactive power compensation capacity per KW is 0.691 kilowatts. Calculate the reactive power compensation capacity according to the capacity of the transformer:

Qc=transformer capacity (KVA)×0.8×0.691

The relationship between 1000 kW and 1000 kVA

1000 kilowatts is the active power power, and the motor power is 1000KW.

1000 kVA is the capacity, and the transformer capacity is 1000KVA, which includes active power and reactive power, because only the purely resistive load power factor is 1, and neither the inductive load nor the capacitive load is 1.

Generally, the load rate of the transformer is about 85%, and 1000KVA can carry a load of about 850KW.
