One of the way out to resolve the issue of harmonics would be using filters in the power system. Installing a filter for nonlinear loads connected in power system would help in reducing the harmonic effect. The filters are widely used for reduction of harmonics.
What is the best solution to reduce harmonics?
Adding a line reactor or transformer in series will significantly reduce harmonics, as well as provide transient protection benefits. Transformer connections can be employed to reduce harmonic currents in three-phase systems.
What are the means to reduce harmonics?
The harmonic content can be brought to a reasonable limit of 5 % by one of the methods, by inserting filters between the load and inverter. If there is a high frequency harmonics, these can be reduced by a low size filter.
