I. Overview

HZJZ-200V transformer ratio standard tester, also known as power frequency induction voltage divider, is a ratio conversion device composed of three interconnected transformers. Through switch switching, the output voltage of the device is equal to a proportional value of the input voltage.It has the advantages of accurate voltage ratio, stability and universal ratio.In addition, the equipment also has the characteristics of high input impedance and low output impedance, which provides important performance for accurate electrical measurement. It is widely used in various measurement lines and devices such as electric power, detection, oil field, railway, school, mine energy and so on.
