Voltage- and Frequency monitor RP 9811 for distributed power generation Systems
With our new voltage- and frequency monitor RP 9811 of the VARIMETER NA family DOLD offers a safe and norm compliant solution for the ideal net monitoring of the supply into the public grid. The preadjusted norms are easy to choose with a rotary switch according to the country specific applications.
If there are ineligible voltage- and frequency values the RP 9811 disconnects the system from the grid.
Our RP 9811 is already equipped with preadjusted parameters for country specific norms or guide lines VDE-AR-N 4105, DIN V VDE V 0126-1-1, BDEW (middle voltage grid), CEI 0-21, ÖVE/ÖNORM E8001_4_712. They will be chosen fast and easy with the rotary switch. Changes of every single parameter are possible individually and menu driven. All required measuring dimensions will be detected continuously from the device. The failsafe RP 9811 is testing and monitoring the connected ripple control switch on availability and function. Occuring failures will be saved chronologically.
A sealable cover, a password and the checksum test of adjusted parameters offer protection against manipulation.
The indication of the plant condition will be effected by a diagnosis via multi colour, illuminated LCD display and LED's.
The VARIMETER NA can be used as an automatic switching point between distributed power generation plants and grid and is valid for the safe disconnection from the grid. Additional inputs allow the integration of your ripple control receiver- and plant concepts.
