Description

GE Reason RPV311 Digital Recorder

GE offers a full measurements portfolio for digital substations covering fault recording (DFR), PMU, transducers and power quality analyzers. GE’s Reason RPV311 Digital Recorder and Bitronics Digital fault recorders allow analysis of power system fault waveforms, power quality issues and network oscillations which could threaten grid stability. Travelling Wave Fault Location pinpoints the location of a fault on a transmission line for precise dispatching of maintenance crews. Phasor Measurement Units measure and communicate real-time power system vector quantities for use in stability and wide area automation schemes.

Phasor measurement, power quality, precision fault location and process bus options deliver the highest integration capabilities for digital substation and wide-area schemes (WAMS).

The RPV architecture is comprised of separate processing and measurement acquisition units, which communicate using dedicated fibre-optic links of up to 2km, allowing flexible installation and mounting. It is possible to install all the units in one panel, in a centralised solution, or it is also possible to install the acquisition units in the protection panels, communicating to one central processing unit. In the distributed architecture the electrical cabling is reduced, since it is not necessary to take all signals to one concentrated DFR panel.
