Disadvantages of Harmonics:

Harmonics degrades the performance of power system. Some of the disadvantages of harmonics in the power distributed network are listed below:

The harmonics flowing in the distribution network downgrade the quality of the electrical power supply. There can have several negative effects on the operation of the power system

Increased losses on the distribution system due to increase in the effective rms current

Over-load in neutral conductors due to cumulative increase in the third harmonics created by the single phase loads

Overloads, vibration and premature ageing of the generators, transformers and motors as well as increase in the noise level

Overloads and premature ageing of the power factor correction capacitors

Distortion of the supply voltage that can disturb the operation of the sensitive loads

Disturbances in the communication networks and telephone lines

Resonance between the supply inductance and capacitance of the power factor correction capacitors
