The Ultimate Guide to 112.5kVA Transformer

What is a 112.5 kVA transformer?

The transformer of 112.5KVA refers to the transformer with a rated power of 112.5KVA.

If we discuss more in the next step, you can also understand that if a transformer can carry the highest operating load under safe operating conditions is 112.5KVA kVA.Then this is a 112.5KVA transformer.

And because KVA is related to the operating power of the transformer, it is the sum of the reactive power when the transformer is not running and the active power when it is running. So if the load resistance of the transformer is loaded, the total operating power value will be exactly the same as KVA.

However, in reality, there are other loads on the operating circuit, and it is impossible to achieve the ideal power factor of 1, so the actual on-load value must be higher than the capacity of the transformer.

How many kilowatts of appliances can a 112.5 kVA transformer drive?

In fact, the power factor of the transformer is generally 0.8-0.85, we can use 0.85. Now the power factor we are using is 0.85. We know the formula for calculating power: power (w) = capacity (kVA) × power factor (COSφ). If it is a 100KVA transformer, the power is 85KW. So a 112.5 kVA transformer can drive 95 kW electrical equipment.

So in general, you can directly check the operating power factor of your power transmission and distribution lines. According to this calculation ratio, you can know how much power the 112.5KVA transformer can supply. This power factor and value will be a very safe value.

How Does A 112 kVA Transformer Operate?

Using the magnetic induction principle, a 112 kVA transformer may step up or step down energies. 

112 kVA transformers have no moving parts and are therefore guaranteed to have a long and trouble-free life under normal conditions. 

In most cases, it is feasible to use a 112 kVA transformer at a voltage that is lower than what is on the nameplate.

No matter how many taps the 112 kVA transformer has, you still can't use it for voltages higher than its rating. As the voltage drops, the KVA power subsides too.

As long as the nameplate VAlue is not exceeded, 112 kVA transformers

can operate at frequencies higher than 60 Hz and up to 400 Hz without being severely damaged. 

Input voltage control capacities of 112 kVA transformers diminish at frequencies of 450 hertz or higher.
