SATEC PMU PRO – IEEE C37.118 Phasor Measurement Unit | WAMS | IEC 61850
SKU: PMU PRO
In stock · Ready to ship
A Phasor Measurement Unit (PMU) – the essential building block for Wide Area Monitoring Systems (WAMS). These systems provide real-time health checks of nation-wide transmission grids, predicting and helping to prevent power failures. By interfacing GPS receivers/clocks or using Precision Time Protocol (PTP), the PMU PRO reaches micro-second precision, providing razor-sharp snapshots of measured parameter angles.
