Technical principle of digital current transformer

- Apr 03, 2021-

Digital transformers (also known as photoelectric transformers, smart transformers, electronic transformers) are essentially different from traditional electromagnetic transformers. Digital transformers output digital signals, while electromagnetic transformers are analog signals (similar to the difference between digital TV and analog TV). It is based on the principle of optoelectronic technology (which is why it is also called photoelectric transformer) and is an indispensable product for the country to build a smart power grid. Photoelectric transformer: including active electronic current transformer and passive magneto-optical glass electronic current transformer.
