Reduction in Harmonics in Marble Industry

Prakash sundaram, Shimi S.L., Dr.S.Chatterji

Lower order harmonic are major problems in industries in India. This will get worse due to the increasing number of lagging power factor induction motors and harmonic generated non linear loads. During survey of Udaipur, Rajasthan (India) investigator found the poor condition of power quality in large number of marble, soft stone and minerals industries and took one marble industry for investigation of the power quality due to harmonic content in power supply. After measurement in Arihant Marble industry, Udaipur, Rajasthan (India), the investigator found that the 5th harmonic content was beyond the IEEE limits. Investigator then design the harmonic filter at Hercules Controls Panel Pvt. Ltd. Udaipur, Rajasthan (India), after installation of harmonic filter at Arihant Marble Industry and measurement were done again and found that 5th harmonic content was below IEEE limits. Investigator also calculate the kVA saving.
