The set of plant diagrams includes:

single-line diagram of the protection: complete representation
of the plant showing the c.t. and v.t. connections to the
protection.

standard cable connections: block diagram showing the
protection equipment cabling (electronic equipment racks to
I/O units).

protection cubicle layout: installation and locations of the
electronic equipment and I/O units.

electronic rack layout: equipment locations within a rack.

measurement circuits (three-phase plant diagram): connection of the c.t's and v.t's to the protection.

auxiliary supply: external connection and internal distribution
of the auxiliary d.c. voltage supply.

I/O signals: external connection and internal wiring of the
tripping and signalling outputs and the external input signals.

The auxiliary supply is switched off by means of a switch on the
auxiliary d.c. supply units 216NG61, resp. 216NG62 or 216NG63.
The following must be noted in this respect:

Every electronic equipment rack is equipped with its own
auxiliary power supply unit.

Either one or a maximum of two redundant 216NG6. auxiliary
d.c. supply units can be installed in an equipment rack.

Where two redundant auxiliary d.c. supply units are fitted,
both units must be switched off.
software permanently stored within the RE. 216 system. The functions required to protect a specific plant can be individually selected, activated and set. A particular protection function may be used several times in different protection schemes. How the signals are to be processed by the protection for the plant in question such as the assignment of tripping, signalling and logic signals to the various inputs and outputs is also determined by appropriately configuring the software. The system hardware is modular in structure. The number of electronic devices and I/O units actually installed, for example, to increase the number of protection functions or for purposes of redundancy, can vary according to the requirements of the particular plant. Because of its modular design and the possibility of selecting protection and other functions by configuring the software, the generator protection REG 216 can be adapted for the protection of small, medium and large generators as well as large motors, power transformers and feeders, while the control unit REC 216 can perform data acquisition and control and supervision functions in medium and high-voltage substations.
