The PCS-996A Phasor Measurement Unit (PMU) is used to measure power system data in real time and report to the network control center for supervision, data storage and backup, system analysis and stability control.

The PCS-996R disturbance recording system provides disturbance record, display and analysis to verify proper operations and analyze existing problems in a power network. The PCS-996R captures the curve forms of the monitored quantities and aligns the values of different supervised objects to build the disturbance record.
