High temperature is the main factor that causes the most likely failure of electronic devices including UPS. At high temperature, the leakage current of the device increases and the voltage decreases. According to Arrhenius’ law, when the ambient temperature is 25 degrees centigrade, the life of components or equipment is reduced by half at 10 degrees centigrade. When the temperature rises according to the arithmetic gradient of 10 degrees, the life of components or equipment will decrease which follow 1/ (n=1, 2, 3…) the law of geometric progression. And the temperature rise inside the machine comes from the power consumption of every circuit in the machine. Transformer is one of them. If there is no transformer, the power consumption can be reduced. So in this sense, because of the existence of transformer, to a certain extent, the reliability of the system is reduced.

The mistake here is to confuse the mechanical stability and electrical performance of transformers. The stability here refers to the stability of the electrical properties. Since the existence of transformers reduces the reliability of the system, of course, it also reduces the stability. People in misunderstandings mistakenly regard the stability of electricity as mechanical stability: the weight of the transformer is large and the center of gravity is stable, so the reliability and stability of the system are guaranteed. Furthermore, the transformer is only a part of the UPS. It does not add trouble to the whole and improves the reliability of the device. If you look at the problem from this point of view, it can be said by any part of the device.
