Proven Benefits that Justify Harmonic Treatment.
- Reduction in fire and safety risks.
- Reduction in energy losses.
- Power Factor improvement
- Avoid potential utility harmonic surcharge
- Lower maintenance costs
- Increased available capacity of Transformers, UPS, Generators. Conductors..
- Less equipment repair and replacement.
|
Absorption filters
- Series L - C absorption fillers are used to absorber harmonic currents.
- De tuned, Partially tuned & tuned filter configuration are commonly used.
|
Harmonics To Design For
- Loads' consisting mainly six pulse converters result harmonics. The problem creating harmonics are normally.
|
a. 5th Harmonic.
b. 7th Harmonic.
c. 11th Harmonic.
d. 13th Harmonic. |
- In most of the cases 5th & 7th are at high level and are filtered that brings THD down.
