What is IEEE Std 519?
ANSI/IEEE Std 519-1992 Recommended Practices and Requirements for Harmonic Control in Electrical Power Systems is the recognized power quality standard in North America. From this standard we wish to provide the following sections: Section 10.3 Limits on Commutation Notching, states that – The notch depth, the total harmonic distortion factor (THD), and the notch area of the line-to-line voltage at PCC should be limited as shown in Table 10.2.
