In May 2019, organized by the China Electric Power Enterprise Federation, a cable online fault positioning product appraisal meeting was held for Three Phase Power Technology Co., Ltd. The organizers of the meeting invited more than 30 industry experts from State Grid, Southern Power Grid, and research institutes.

Our company's project leader gave a detailed introduction to the product technology and its characteristics to the attending experts, and compared it with relevant technologies at home and abroad. Finally, we reported on the pilot application of our independently developed cable online fault location product.

The experts of the appraisal committee have recognized our company's new cable products and unanimously believe that the cable online fault location product developed by Wuhan Three Phase Power Company has reached the leading level in China as a whole. They agree to pass the product appraisal and recommend promoting its use.
