PROFICIENCY TESTING

Relying on national-level centers such as the National Center for Quality Inspection and Testing of High-Voltage Electrical Apparatus, the National Center for Quality Inspection and Testing of Insulators and Surge Arresters, the National Center for Quality Inspection and Testing of Power Capacitors, the National Center for Quality Inspection and Testing of Intelligent Electrical Equipment, and the National Industrial Metrology and Testing Center for Transmission and Distribution Equipment, a proficiency testing provider system was established in August 2022 and has been operated in a standardized manner. The organization has successively conducted proficiency testing activities for loop resistance measurement and power-frequency voltage, and in May 2024 obtained CNAS accreditation (Registration No.: CNAS PTO141), becoming a CNAS‑accredited entity specializing in laboratory proficiency testing and measurement audits.
