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
network are listed below :
