4.8.3 VDE-AR-N 4110:2018-11 – basic program 4110
Application/Use: higher-level decoupling protection of the generating plant without
QU protection in the context of VDE-AR-N 4110:2019-11.
Automatic reconnection is not permitted after a disconnection due to a tripped protec-
tive or monitoring function of the generating plant. Reconnection may only take place
after approval by the network control centre.
(VDE-AR-N 4110:2018-11 chapter 10.4.2 par. 1)
In order to meet this requirement with the VDM460-NA, the use of the remote trip func-
tion (remote disconnection) in conjunction with an external circuit must be implement-
ed. The following wiring diagram and the corresponding explanation is only one
possible example:
