AREVA’s MiCOM P847 PMU (Phasor Measurement Unit) modules can be applied to monitor strategic busses and corridors in the transmission system. The applications include On-line and offline wide area monitoring and analysis systems as well as Real time stability control.

The P847 has a set of VTs and CTs used for phasor measurements. Additional system protection functions such as frequency, voltage, circuit breaker monitoring and recording functions are included in the P847 device.

In an advanced setting, this technology complements traditional SCADA in enhancing operator decision making from a reactive to a more response based decision process.
