Well researched and documented real-industry live case studies covering a wide rage of Industries and PQ issues from Asia on harmonic distortions, under-voltage and over-voltage, voltage dips, sags, flicker/sag/swell, transients, earthing, reactive compensation and so on , are available here for downloading. The case studies offer detailed analysis of the PQ issues ad solutions including economic analysis to enable users and top managements to readily go in for implementable economical solutions.
The communication equipment’s are increasingly sensitive to power quality issues especially in terms of performance, requiring following of various international standards and procedures in dealing with grounding issues and avoidance of interferences from other sources.
Whenever plant undergoes modernization, basically several types of non-linear loads are added newly in the process fresh PQ audit would help in identifying areas of concern. The location of non-linear loads play a vital role, which may yield even further engineering solutions in managing & mitigating the harmonics as explained in this case study.
Power Quality is a measure of an ideal power supply system. The most obvious defects in power supply system are complete interruption (which may last from a few seconds to several hours) and voltage dips or sags where the voltage drops to a lower value for a short duration.
The modern electronic controllers are added in the industries for having refined control for the process and enhancing the efficiency of the system. These are also added as retrofit in subsequent years to operationalization of plant. These are classified as non-linear loads.
The case study looks into the effect of poor power quality and harmonic distortion resulting in disturbances like, overheated cable, temperature rise in transformer and spurious breaker tripping's at a sponge iron manufacturing unit located in an Indian integrated steel plant. The study also suggests few mitigation techniques which while adopted result in substantial cost savings
