Maturing photoelectric transformer instead of the traditional electromagnetic transformer

The use of increasingly sophisticated photoelectric transformer instead of the traditional electromagnetic transformer, power grid construction and transformation to achieve far-reaching significance. Straight people hot topic. In  electri cenergy meter , the temperature variation errors of measurement, one should increase the optical system (such as the light source, optical, electro-optical crystal) and a photodetector (such as a photodiode) of the anti-jamming capability, such as  Voltage stabilizer and a small light source wavelength shift, pure and after several electro-optic crystal pulling and so on. Also in the temperature stability of the study, scholars much attention recently with temperature control method, two optical temperature compensation method, two crystal temperature compensation circuit compensates for hardware and software compensation method.
