Harmonic Analysis Study

HARMONIC ANALYSIS STUDY
Perspective:

Harmonics are AC Voltages and Currents with frequencies with integral multiples of the fundamental frequency. Rapid advancement of power electronics in the industrial applications makes industrial load non-linear which generates harmonics. Since the load is non – linear, the current will be distorted and become non – sinusoidal. Harmonics arise from inverters, VFDs, rectifiers, voltage controllers, frequency controllers and other semiconductor switching devices generators, transformers, welders and arc furnaces.

Cholamandalam MS Risk Services Limited (CMSRSL) offers Harmonic Study Analysis as preventive maintenance to safeguard electrical and electronic equipments from damage due to rise in harmonic levels.
