Example:
Generator 13.8 kV ; 4 kA
C.t’s/v.t’s 14400/120 V; 5000/5 A
Protection 100 V; 5 A

0 800.
The reference value of 0.8 determined in the above example for
the current channels means that at a full load current of 4000 A,
a current of 4 A flows on the secondary side of the c.t’s which for
the protection is the 100 % load current. The settings on the
protection are then directly referred to the rated current of the
protected unit.
Effects of changing the reference values:
The protection function settings (parameters expressed in
relation to ‘IN’ and ‘UN’) are automatically adjusted to the new
reference values.
Edit A/D channel comment
Facility is provided for the user to enter a comment for each
analogue channel, which is displayed together with the channel
type when the corresponding c.t. or v.t. input parameter of a
protection function is selected.
3.4.3. Entering comments for binary inputs and outputs
(see Section 5.5.5.)
Individual comments can be entered for each binary input and
each signalling or tripping output. This operation is carried out
via the menu ‘Edit hardware functions’ and then ‘Edit binary
inputs’, ‘Edit trip outputs’ and ‘Edit signal outputs’.
