Photoelectric Transformer basic principles and advantages of photoelectric transformer according to different sensor head design principles

Photoelectric Transformer basic principles and advantages of photoelectric transformer by sensing head design principles can be divided into active-and passive-type; accordance measuring the content can be divided into electronic voltage  Voltage stabilizer  electronic TVE type current transformer. Active-type photoelectric current transformer is the principle of Rogowski coil sensor head partly achieved  mcb circuit breaker  and then turn it into a light signal to the low-pressure part of the processing. Passive type optical current transformer is the use of the Faraday effect, a beam of linearly polarized light through the optical material is placed in a magnetic field, the plane of polarization of the linearly polarized light will be rotated, the rotation angle and the measured proportional to the current.
