Digital fault recorder RPV311

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.
