harmonicIt refers to the amount of electricity contained in the current with a frequency that is an integer multiple of the fundamental frequency. Generally, it refers to the Fourier series decomposition of periodic non sinusoidal electricity. Except for the electricity at the fundamental frequency, the electricity generated by currents greater than the fundamental frequency is called harmonics. The harmonic frequency is the ratio of the harmonic frequency to the fundamental frequency (n=fn/f1).

Reactive power is the electrical power used for the exchange of electric and magnetic fields within a circuit, and for establishing and maintaining a magnetic field in electrical equipment. It does not perform external work, but is converted into other forms of energy. Any electrical equipment with electromagnetic coils that establishes a magnetic field requires the consumption of reactive power. Reactive power does not do any work, but to ensure the conduction of active power, it must first meet the reactive power of the power grid.
