With the rapid development of photonics technology Wuhan High Voltage Transformers, many developed countries have already turned to technology using optical sensor technology and electronics to develop new methods of electronic current transformer high voltage transformer, short optical current transformer. International Electrotechnical Commission has published a standard electronic current transformer. Meaning Huzhou electronic transformer high voltage transformer, in addition to including the photoelectric transformer, also includes a variety of other electronic test principle of voltage and current sensors. High voltage transformers are suitable for 1kv to 220kv power system will be a large voltage into a small voltage or high current in order to convert the small current measurement, protection, transformer used generally divided 3kv, 6kv, 10kv, 35kv, 66kv , 110kv, 220kv, 24kv system in Jiangsu Province is now the trial. 10kv and 220kv among the most widely used. The second input of 200V or 100V or more 5A or 1A. Huzhou high voltage transformer, Huayi Electric Power (certified), high-voltage transformers supplied by Xian Huayi power plant. Xian Huayi power plant (www.xahy.com) is a leader in Xi'an, high voltage circuit breakers, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Huayi power in leadership with the staff warmly welcome all inquiries negotiations to create electricity Huayi a better future.
