GB/T 16896.1-2005

This standard specifies the performance requirements, calibration methods, and accuracy criteria for instruments used in high-voltage impulse tests, such as lightning and switching impulse voltage measurements. It is applied in high-voltage laboratories and testing facilities for power equipment, including transformers, insulators, and surge arresters, to ensure reliable measurement of impulse waveforms. The standard is critical for validating the insulation performance and safety of electrical apparatus under transient overvoltage conditions.
