Frequently Asked Questions
What is a power quality measurement record?
A power quality measurement record documents measured voltage and current parameters — THD, individual harmonics, voltage imbalance, power factor, and flicker — at specific points in the electrical system. It is used for IEEE 519 and IEC 61000 compliance verification and troubleshooting power quality issues.
What should a power quality record include?
Key fields include measurement point, nominal and measured voltage, voltage THD, voltage imbalance, per-phase current, neutral current, current THD, individual harmonic levels (3rd through 13th), true and displacement power factor, frequency, flicker indices, and measurement duration.
What are the IEEE 519 harmonic limits?
IEEE 519 Table 2 limits current THD based on the Isc/IL ratio at the PCC. For typical systems (20<Isc/IL<50): individual odd harmonics limited to 7% (3rd–11th) and total current THD to 8%. Voltage THD is limited to 5% for systems below 69kV (Table 1). Even harmonics are limited to 25% of odd harmonic limits.
