【 摘 要 】

Today is much attention paid to power quality, especially in deragulatedelectricity market. Voltage dips and short power supply interruptionsare the most frequently problems in this area. Every voltage dip can becategorized in to the one of the seven categories which are differ onvoltage phasor diagrams in steady state. Correct categorisation of thisvectors can reveal the cause of voltage dip and voltage level, in whichvoltage dip originate. It is importatn to know the transformers windingconnection, which can change the voltage phasor diagram in complex planean can have the negative influence on categorisation of the voltage dipin to the correct category.
