What is the voltage change rate of 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 is bound to drop. Compare the voltage drop value with the rated voltage value, take a percentage, that is, the voltage change rate, which can be expressed by the formula; the voltage change rate = [(secondary rated voltage load terminal voltage) / secondary rated voltage] × 100%. The voltage change rate of a common power transformer is 4-6% when it is connected to the rated load.
