T/CQPRA 0099-2026 Technical Specification for Accuracy Evaluation of Cable Fault Early Warning and Location Devices
Basic Information
Scope
This document is applicable to the accuracy evaluation of power cables (including medium- and low-voltage, high-voltage, and extra-high-voltage cables) in the research and development, factory testing, project acceptance, and operation evaluation stages. This document is applicable to cable fault warning and location systems based on technologies such as online monitoring, inspection detection, and multi-source data integration. It can also provide a basis for performance testing and result evaluation by relevant inspection agencies, operation and maintenance units, and third-party evaluation organizations. This document specifies the basic requirements for the accuracy evaluation of cable fault warning and location devices, including evaluation principles, indicator systems, test methods, accuracy calculation, grading determination, and result application, etc.
