Скачать или смотреть How to extract filtered phasors from actual field events for efficient analysis..

These custom calculations sheets have been created for use in conjunction with the SEL SynchroWAVe Event software in order to provide various types of filters or measuring modes that commonly used in most of protection relays.

Those filters can be utilized to extract filtered phasors and other quantities from Raw or COMTRADE records, and offer more advanced and efficient analysis that may needed to confirm the correct operation of protection relays algorithms while investigating actual field cases. And such filters includes:

▪︎ Half and full cycle DFT filter.
▪︎ Half and full cycle Cosine filter.
▪︎ True RMS filter.
▪︎ Peak-to-peak filter.
▪︎ Generate raw phasors for time-series signals.
