This paper mainly focuses on the causes for the series reactor failures and 11KV protection monitoring power system components. Failure causes the harmonics, transients and other power quality related problems. Power quality is the major concern of our modern industries and other consumers. Poor quality of power supply will affect the performance of customer equipments such as computers, microprocessors, adjustable speed drives, power electronic devices, etc. Due the production problem, the major industries get financial losses to the customers, loss of life in hospitals etc. The two major power quality disturbances are voltage sag and harmonic distortion. In the event of voltage sag due to insufficient energy supply, equipments may malfunction or trip. Another disturbance of Harmonics introduced by nonlinear loads can pollute the input supply to the sensitive equipments and be a cause for the connected equipments to malfunction. In this paper, a Power Quality Provider is proposed and modeled by simulation with the help of an external agencies meter. © 2014 Elsevier B.V., All rights reserved.
