IEEE Std 519

IEEE Std 519 is a guideline established by the Institute of Electrical and Electronics Engineers to help manage electrical power quality in systems. It focuses on controlling voltage and current distortions caused by non-linear loads, such as computers and lights. By setting limits on harmonic distortion—the unwanted frequencies that can interfere with equipment—this standard aims to ensure the reliability and efficiency of electrical systems. Following IEEE Std 519 helps prevent damage to devices, reduces energy waste, and promotes the overall stability of power networks.
