As Guanggao Electric marches toward new heights in power equipment testing, exciting news arrives! Recently, leveraging its outstanding technical strength and rigorous quality control system, the company successfully passed the lightning impulse voltage waveform front-time measurement proficiency test organized by Guangdong Product Quality Supervision and Inspection Institute. This marks the company’s leading position in transformer testing technology in the industry, providing a more solid guarantee for the safe and stable operation of power systems. Lightning impulse voltage test is a key link in evaluating transformer insulation performance. As a crucial parameter for measuring lightning impulse voltage waveforms, front-time accuracy directly affects the performance evaluation of transformers under transient overvoltage conditions like lightning. This proficiency test gathered many authoritative institutions and outstanding enterprises in the industry, with extremely fierce competition. Facing strict testing standards and complex verification procedures, Guanggao’s technical team rose to the challenge. To ensure the smooth passage of this proficiency test, the company made careful preparations months in advance. Technical backbones conducted in-depth research on the latest industry standards and specifications, fully upgraded and calibrated measurement equipment, and repeatedly optimized measurement schemes. During the verification process, team members operated each link accurately with exquisite professional skills and rich practical experience, strictly controlled data collection and analysis, and finally completed the task with excellent results. The accuracy and reliability of the measurement results were highly recognized by the verification institution. Successfully passing this proficiency test is an important milestone in Guanggao’s development. It not only demonstrates the company’s profound accumulation in transformer testing technology but also reflects its unremitting pursuit of product quality and technological innovation. For a long time, Guanggao has always adhered to the development concept of "taking technology as the core and quality as the life", continuously increasing R&D investment, introducing advanced technologies and equipment, and cultivating professional talent teams. Looking ahead, taking this as an opportunity, Guanggao will continue to improve its technological innovation capabilities and service levels, expand the breadth and depth of the testing field, and provide customers with more high-quality and reliable transformer testing solutions. It will continue to work with industry partners to jointly promote the progress of power equipment testing technology and contribute more to building a safe, efficient and stable power system!
