4 Factors To Consider When Opting For A Passive Harmonic Filter

Harmonic filters are critical for improving power quality and reducing distortion. However, not all harmonic filters are the same. There are three main choices to consider, active harmonic filters, passive harmonic filters and hybrid harmonic filters. While active harmonic filters are ideal for top performance, passive filters also have their applications. However, it is important to know when to opt for passive harmonic filters. This blog explores 4 such factors.

When To Go For A Passive Harmonic Filter

Nature Of Harmonics

If the harmonic distortion is from a singular source and is predictable, such as if the harmonics are of a fixed order, then it is best to choose passive filters. But if the distortion is from multiple sources, then active harmonic filters are the better choice.

Cost Effectiveness

If cost-effectiveness during installation and setup is important, then passive harmonic filters are a great choice. However, this is applicable only if the load is large, singular, and non-linear. If this is not the case, then active harmonic filters or hybrid filters can be considered.

Easy Maintenance

Installing a harmonic filter is quite different from maintaining it in the long run. Passive harmonic filters are a great choice in this case as they don’t require a lot of upkeep. Provided the conditions mentioned above are met, passive filters are excellent from a low-maintenance perspective.

Space Constraints

Lastly, a major drawback of passive harmonic filters is their size. Choosing the right size can be a challenge, especially if there are spatial constraints. However, if this is not a concern, then going for passive filters can be ideal.
