I. Overview
1. 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.
