Voltage Transformer or Potential Transformer – Explained

by

A voltage transformer is a type of instrument transformer. We also call it a potential transformer. It reduces high voltage to a lower and measurable value according to its turns ratio. We need to measure the voltage in extra-high-voltage (EHV) systems. However, a normal measuring instrument cannot measure such high voltages directly. So, a voltage … Read more

What is the Rated Voltage Factor in voltage transformers, and how is it determined? This is the ratio of the maximum operating voltage to the rated primary voltage of the PT. We have to multiply this factor by the primary rated voltage. This determines the maximum operating voltage of the PT. In other words, this … Read more
