ActiveHigh voltage and high current test techniques―Part 4: Definitions and requirements for test currents and measuring systems
高电压和大电流试验技术 第4部分：试验电流和测量系统的定义和要求
Application Summary AI generated
This standard defines the characteristics, measurement requirements, and calibration procedures for test currents used in high-voltage and high-current testing, specifically for power equipment like transformers and switchgear. It is applied in electrical engineering laboratories and testing facilities to ensure consistent and accurate measurement of impulse, alternating, and direct currents during type and routine tests. The standard also specifies performance criteria for measuring systems, including their response and uncertainty, to validate equipment compliance with safety and operational standards.
