ActiveInstrument transformers—Part 103：The use of instrument transformers for power quality measurement
互感器 第103部分：互感器在电能质量测量中的应用
Application Summary AI generated
This standard specifies the application requirements and performance criteria for instrument transformers (voltage and current transformers) when used specifically for power quality measurements, such as assessing harmonics, interharmonics, and flicker. It is applied in electrical power systems, including substations, industrial facilities, and grid monitoring points, where accurate measurement of power quality parameters is essential for compliance and system analysis. The standard ensures that the transformers' accuracy and frequency response are suitable for these specialized measurement tasks.
