Standards-Based Investigation of Voltage Dips and Voltage Imbalances in an Organized Industrial Zone
MetadataShow full item record
The measurement, monitoring and evaluation of power quality have a great importance for avoiding grid- and device-based problems in the stages of generation, transmission, distribution and consumption of electrical energy. For this purpose, several standards have been set up in order to minimize the effects distorting the power quality of power systems in our country and in the world. In case of investigating these standards, it is mined that voltage dips and voltage imbalances are among the significant technical quality parameters for power systems. In this study, the voltage dips and voltage imbalances occurred in the phase-to-phase effective voltages of a medium-voltage transformer located in an organized industrial zone have been analyzed according to the standards. The number of higher voltage dips and the ratios of excessive voltage imbalances are uncovered and many reasonable assessments are made for them.
