| Summary: | Today is much attention paid to power quality, especially in deragulated electricity market. Voltage dips and short power supply interruptions are the most frequently problems in this area. Every voltage dip can be categorized in to the one of the seven categories which are differ on voltage phasor diagrams in steady state. Correct categorisation of this vectors can reveal the cause of voltage dip and voltage level, in which voltage dip originate. It is importatn to know the transformers winding connection, which can change the voltage phasor diagram in complex plane an can have the negative influence on categorisation of the voltage dip in to the correct category. |
