Electronic temperature measurement technique（thermal resistance、thermocouple）has been very mature and stable in the field of detection of dry-type transformers temperature and ensuring the safety operation of dry-type transformers. But with the continuous innovation in technology of dry-type transformer and the rising requirements on the transformer grade, we found in recent years that the adoption of electronic temperature control are vulnerable to the high-pressure and high-frequency electromagnetic interference. This further results in temperature beating or failure. Eventually, it will cause transformer trip, which will bring direct or indirect economic loss to the users, or even induce transformer explosion, the consequences could be disastrous.

        According to statistics, in all kinds of new high-grade dry-type transformers, when the transformer’s rated capacity reach to 10000KVA and above, or the transformer’s low end of rated voltage is up to 10KV and above, the internal transformer will generate strong electromagnetic interference, electronic temperature control equipment can not work in such conditions. So exactly what kind of technical solutions that can solve the problems that dry-type transformer being embedded inside the winding and without any interference, meanwhile have lower overall costs for security monitoring needs? The experts gradually realized that in the field of temperature measurement, optical sensing measurement is the best way to solve this technical bottleneck. While among several working principles of optical sensing temperature measurement, only fluorescent optical fiber temperature measurement is able to meet all these three important requirements at the same time. We can say that, the fluorescent optical fiber temperature measurement technology is born for the new dry-type transformers!

        And the fact indeed confirms this point. Through independent principle development, and professional industrial operation, we improve system quality and pay attention to processes, control costs and pursue stability, actively to the scene and collect customer’s feedback, our company has realized a continuous supply for the stable and reliable “fiber temperature controller dedicated for the dry transformer” in the shortest possible time. The products won the approval of majority users and a good reputation in the industry. The high-end dry-type transformers which use our product for safety monitoring, are all applied in the national or provincial and municipal key projects, such as West East Gas Pipeline Project, the South to North Water Diversion Project, High-speed Rail Distribution, The CNG project, City Metro Distribution and so on. As with the gradually improved influence of the company's products in this industry and by virtue of the price advantage of domestic brands, our products are more well-known by international clients. As a Chinese brand, we must take advantage of this opportunity to showcasing Chinese style!
