Open the catalog to page 1

Network and system protection (NS protection) for monitoring the network feed-in from generating plants Product description The VMD460-NA is intended for protecting the network and the (generating) plant from inadmissible operating states and disconnecting them. For this purpose, the VMD460-NA is designed according to the single-fault tolerance principles. If the switch-on conditions or (re-)connection conditions are fulfilled, the VMD460-NA enables the coupling of the generating plant to the network. Details are regulated by the applicable (application) standards and guidelines. The...

Network and system protection (NS protection) LINETRAXX® VMD460 Wiring diagram VMD460 (VDE-AR-N 4110:2018-11 – basic program 4110) Within the scope of VDE-AR-N 4110:2018-11, the VMD460-NA can be used as protective disconnection device for the generating unit or as higher-level protective disconnection, the latter, however, only if the Q-U protection function may be dispensed with. According to VDE-AR-N 4110:2018-11 chapter 10.3.3.4 par. 5, this is possible after consultation with the network operator and under the following conditions: • Generating plants with limited dynamic network...
