The basic principle of photoelectric transformer waves through the magneto-optical material whose plane of polarization is rotated

With fiber-optic sensing technology, optical fiber communication technology, the rapid development of photovoltaic technology in the power system more widely . Photoelectric Transformer is one of them . Photoelectric transformer with small size, light weight, band response width , no saturation phenomenon , anti- air circuit breaker  interference , good performance, oil-free structure , insulation , reliable, easy to digital, computer development and many other advantages , in digital substation widely application . Meanwhile , intelligent switches, photoelectric transformer , a run -line state detection equipment , substation operator  power transformers  technology matures , and computer high-speed network in the development and application of real-time systems , substation automation systems are moving to an all digital direction . The basic principle of  circuit breakers  light through optical materials will occur when the polarization plane rotation, rotation angle measured to determine the size of the measured current . Passive type photoelectric transformer does not require high-pressure part of its electronic circuits and has a more compact structure and more reliable impact resistant insulated surge current capability and capacity , is the true meaning of optoelectronic products.
