Question

How can third harmonics be reduced?


Open in App
Solution

Explanation:

Certain methods can be used to reduce harmonics they are:

  1. Adding a line reactor or transformer in series will significantly reduce harmonics, as well as provide transient protection benefits.
  2. Isolation transformers provide a good solution in many cases to mitigate harmonics generated by non-linear loads.
  3. Isolation transformers can reduce the third harmonic which is created due to the usage of the delta to a star configuration
  4. Active filters are widely used, in many industrial applications. These filters can reduce harmonics and reactive power compensation.

Hence, in this way, third harmonics can be reduced.
