The Ultimate Guide to 112.5kVA Transformer

What is a 112.5 kVA transformer?

A 112.5 kVA transformer refers to a transformer rated at 112.5 kilovolt-amperes (kVA), which indicates its capacity to handle electrical loads under safe operating conditions. The kVA rating represents the total apparent power that the transformer can deliver, combining both the active (real) power and the reactive power.

In practical terms, the rated kVA of a transformer denotes the maximum load it can reliably support. For instance, a 112.5 kVA transformer can handle a maximum combined load of active and reactive power up to its rated capacity without overheating or other operational issues, assuming an ideal power factor of 1 (unity power factor). However, real-world electrical systems often have varying power factors due to factors like inductive loads, which means the actual load on the transformer may exceed its rated kVA to compensate for reactive power requirements.

Therefore, while a 112.5 kVA transformer is rated to handle up to 112.5 kilovolt-amperes of total power, the actual operating load may need to be carefully managed to ensure the transformer operates within safe limits and remains efficient.
