CosPower's Passive Harmonic Filters

Experience Harmonic Mitigation with CosPower Solutions

In the dynamic landscape of modern industries, non-linear loads, ushering in the era of harmonics. At CosPower, we specialize in harmonics management, offering tailored solutions to mitigate their impact and ensure efficient electrical performance.

Understanding Harmonics: The Silent Disruptors

Harmonics, the silent disruptors of electrical systems, wreak havoc with their current distortions, causing impedance variations and voltage irregularities. From overloading machines and damaging electronic equipment to stressing cables and insulation, the ill-effects of harmonics are far-reaching, leading to transformer overload, protection device malfunctions, and even frequent breakdowns, resulting in production and revenue losses. At CosPower, we understand these challenges and provide proactive solutions to counteract them.

Limits of Harmonics Levels as per IEEE 519

< 11 11 to 17 17 to 23 23 to 35 > 35
< 20 4.0 2.0 1.5 0.6 0.3 0.3 5.0
20 < 50 7.0 3.5 2.5 1.0 0.5 0.8 8.0
50 < 100 10.0 4.5 4.0 1.5 0.7 0.7 12.0
100 < 1000 12.0 5.5 5.0 2.0 1.0 1.0 15.0
> 1000 15.0 7.0 6.0 2.5 1.4 1.4 20.0
Bus Voltage at PCC Individual Voltage Distortion Total Voltage Distortion
V ≤ 1.0 kV 5.0 8.0
1 kV < V ≤ 69 kV 3.0 5.0
69 kV < V ≤ 161 kV 1.5 2.5
161 kV < V 1.0 1.5
Even Harmonics: are limited to 25% of the Odd harmonic limits above.

Where:
Isc = Maximum Short Circuit Current at the PCC
IL = Maximum Demand Load Current (fundamental frequency) at the Point of PCC
Note: High voltage systems can have up to 2.0% THD where the cause is an HVDC terminal that will attenuate by the time it is tapped for a user.
