What is harmonics. How does it get generated and means to
arrest harmonics
Answer Posted / hazem el-henawy
Harmonics are integral multiples of some fundamental
frequency ,if the fundamental frequency is f, the harmonics
have frequencies 2f, 3f, 4f, . . . etc., when added
together, result in a distorted waveform, It generates due
to improper switching action, they disturbance the Grid and
equipments.
filters generates Harmonics of opposite polarity to system
Harmonics to nullify the effects,We use filters to get a
stable system.

What are the disadvantages of thermal power plant?
In a power conditoining unit (inverter) of a solar plant when we measure the d.c. current fed by different strings of solar plates to inverter, the current in the negative wire is less almost by 1 ampere to the current in its positive wire say current in positive wire 5 A , then current in negative wire of the same string is 4 A. Since the current entering should be equal to current leaving then why the current is noticably less in negative wire.
