IEEE 519-2014 Voltage distortion limits

For Electrical Network with non linear loads, Voltage Distortion limits are defined in IEEE 519. To ensure Quality Power Supply to Assets, Mitigate !!

Bus Voltage V at PCC	Individual Harmonic (%)	Total Harmonic Distortion (% THD)
V <= 1.0 KV	5.0	8.0
1KV < V <= 69 KV	3.0	5.0
69 KV < V <= 161 KV	1.5	2.5
161 KV < V	1.0	1.5
