3.1.1.1 Description of configuration A20
SEMOD175637-4 v5
REG670 A20 configuration is used in applications where only generator protection
within one IED is required. REG670 A20 is always delivered in 1/2 of 19" case size.
Thus only 12 analogue inputs are available. This configuration includes generator low
impedance, differential protection and all other typically required generator protection
functions. Note that 100% stator earth fault function and Pole Slip protection function
are optional.
REG670 A20 functional library includes additional functions, which are not
configured, such as additional Overcurrent protection, additional Multipurpose
protection functions, Synchronizing function, and so on. It is as well possible to order
optional two-winding transformer differential or high impedance differential protection
functions which than can be used instead of basic low-impedance generator differential
protection. Note that REG670 A20 must be re-configured if any additional or optional
functions are used.
