IEEE 519-2014: Recommended Practice & Requirements for Harmonic Control

The IEEE 519-2014 standard is a recommended practice and requirement for harmonic control in an electric power system’s design. Harmonic control in electric power systems is essential, and IEEE 519-2014 is an updated standard that provides conditions and limitations for products such as power loggers and power quality analyzers . 

Updated IEEE 519-1992

Formally the 519-1992, the IEEE 519-2014 sets a precedent for electrical systems with linear and nonlinear loads. The standard gives objectives for waveform distortion, steady-state limitations, transient conditions, and more. According to the IEEE Standards Association “The interface between sources and loads is described as the point of common coupling and observance of the design goals will reduce interference between electrical equipment.” Power quality becomes the variable to consider at that common coupling point.
 

IEEE 519-2014 Standard Compliance

The board updated this standard in the June of 2014. The IEEE 519-2014 supersedes the IEEE 519-1992 standard, which was previously used for harmonic control, ac power distribution limits, and other requirements. The IEEE 519-2014 focuses on harmonic measurements, statistical evaluation, voltage waveform limits, and current distortion. The IEEE 519-2014 is still an active industry standard, but it is relevant to note that IEEE 519-2014 was superseded by the most recent IEEE 519-2022 standard in May of 2022.
 

Focuses of the IEEE 519-2022 Standard

• Harmonic control
• Steady-state limitations
• Transient conditions
• Statistical evaluation
• Waveform limits
• Current distortion
• Common coupling point (CCP)
• Power quality

ATEC’s IEEE 519-2014 Compliant Products

ATEC carries several products that meet these conditions and fall under this standard. Technicians can survey power quality and complete in-depth analysis with power loggers in accordance with this test standard IEEE 519-2014. To find specific testers that meet this standard, take a look at our selection of power logger and PQA solutions from industry-leading manufacturers Fluke, Dranetz, and more.
