Background/Objectives: Objective of study is discussing about the harmonic effect on electrical apparatus as well as its mitigation methods. Then power quality analysis is performed to four textile and one coffee rural industries. Methods/ Statistical Analysis: The power quality analysis is performed by using Clamp on Power meter. It is measured voltage, load current, power component variations and total harmonic distortion on industries. The measurement was carried out at supply fed end. Findings: Review shows, the growth of electronic components on power system causes harmonic distortion. Although, rapid capacity addition of renewable energy resources on the conventional grid injecting harmonic distortion on electrical networking. These power quality issues are reduced life span of electrical utilities. Hence, these power quality issues are rectified by suitable compensating devices. The total harmonic distortion on textile industries is much higher that of the coffee industry. Since textile industry is used variable speed drives, whereas content speed motors are used in the coffee industry. Also voltage swell is occurs on all industry but it within limit. The harmonic suppressing technique is needed in present day trend. In addition, Load management system in a textile industry is poor. So reforms the load management systems in industries is also recommended. Applications/Improvements: Textile industry and Coffee industry
Keywords: Coffee Industry, Current Harmonics, Clamp on Power Meter, Harmonic Analysis, Textile Industry, Voltage Fluctuation
