Red 670 abb manual

Technical data To accomplish this, three separate communication channels, that is, one per phase, each capable of transmitting a signal in each direction is required. Current reversal and weak-end infeed … It can record disturbances not detected by protection functions. The disturbance recorder information for the last disturbances are saved in the IED and the local HMI is used to view the list of recordings.

These events are created from any available signal in the … Table Differential protection Table Line differential protect … The packages are configured and ready for direct use.

Optional functions are not configured but a maximum configuration with all optional functions are available as template in the graphical configuration tool. Communication protocol manual, IEC, series version 2.

Relion Protection, control and monitoring. REV: T. Drawings and diagrams are not binding. Available functions Main protection functions Table 1. Both two- and three-winding transformers are Line differential protection 3 or 6 CT sets, with in-zone Channels en Five terminal line with master-slave system Current samples from IEDs located geographically apart from The communication link is continuously monitored, and an Typical quadrilateral distance protection zone with Phase Figure This makes them suitable, together with different also important information about faulty phase s , which can be communication schemes, for the protection of power lines and used for fault analysis.

Therefore, the function has a built in algorithm for load can even be decided separate for the phase-to-ground or encroachment, which gives the possibility to enlarge the phase-to-phase loops. If the connection between the generators is too weak the phase, when each group is equipped with current transformers.

Voltage protection current transformers and the open disconnector. It is The output for each limit is activated introduced to enable translating the integer output signal from when the counted value reaches that limit. The LHMI is used for setting, monitoring and controlling.
