How to select transformer? How to determine the reasonable capacity of transformer?
First, investigate the power supply voltage of the power consumption place, the actual power load of the user and the local conditions, and then select one by one with reference to the technical data marked on the transformer nameplate. Generally, the transformer capacity, voltage, current and environmental conditions should be considered comprehensively. The capacity selection should determine the required load according to the capacity, nature and service time of the user's electrical equipment, so as to select the transformer capacity.

What are the losses of transformers in operation? How to reduce losses?
(1) It is caused by the iron core. When the coil is energized, the magnetic lines of force are alternating, causing eddy current and hysteresis loss in the iron core. This loss is collectively called iron loss.

What is the voltage change rate of a transformer?
The voltage change rate of voltage regulator is one of the main performance indexes of transformer. When the transformer supplies power to the load, the voltage at the load end of the transformer will inevitably decrease. Compare the decreased voltage value with the rated voltage value, and take the percentage as the voltage change rate, which can be expressed by the formula; Voltage change rate=[(secondary rated voltage load terminal voltage)/secondary rated voltage] × 100%。 Generally, when the power transformer is connected to the rated load, the voltage change rate is 4-6%.

How is the voltage regulator regulated?
The structure of the voltage regulator is the same as that of the autotransformer, except that the iron core is wound on the ring iron core as a ring coil. A sliding brush contact is used for the tap of the secondary coil to make the contact slip along the loop of the coil surface to achieve smooth voltage regulation.
