Harmonic Analysis
Overview
Harmonic analysis is a technique used to study and analyze the harmonic components in a periodic waveform or signal. The main use of harmonic analysis in electrical engineering is to examine the existence and properties of harmonics in electrical power systems. Harmonic voltage or current waveform frequencies are integer multiples of the fundamental frequency. However, due to non-linear loads, such as power electronics, variable speed drives, and certain types of lighting, harmonic currents and voltages can be introduced into the system.

Suggestions
Option 1: What are the advantages of using Harmonic Filter (Detuned) Reactor?
- Prevents harmonic current and voltage amplitude from increasing in systems with non-linear loads.
- Limits the harmonic current flowing on the capacitor. This prevents heat and high current stresses and allows the capacitors to have a longer operating life.
- Prevents to overcurrent and heating problems on transformers, bus bars, cables, switchgear, protection equipment, etc.
Option 2: Install the Active filter
- Install the Active filter In the plant for reduce the harmonic.

Energy Audit is defined as “the verification, monitoring and analysis of use of energy including submission of technical report containing recommendations for improving energy efficiency with cost benefit analysis and an action plan to reduce energy consumption”. It builds on the principle "you can't manage what you don't measure". It essentially combines the principles of energy use and statistics.
Energy conservation is the effort made to reduce the consumption of energy by using less of an energy service. This can be achieved either by using energy more efficiently (using less energy for a constant service) or by reducing the amount of service used (for example, by driving less).
A compressed air audit effectively identifies inefficiencies, reduces energy costs, and improves system performance. Many industrial air compressors operate inefficiently due to leaks, artificial demand, and incorrect air pressure requirements, unnecessarily increasing cost per kWh.
