REG 316*4 1MRB520049-Uen / Rev. F
s2
Vector group for winding 2.
Settings provided: All usual groups of connection with
designation of the circuit (y = star, d = delta, z = zigzag)
·
phase-angle adjustment of the winding 2 voltage in rela-
·
tion to the winding 1 voltage in multiples of 30°.
CurrentInp2
defines the c.t. input channel for winding 2. The first channel
(R phase) of the two groups of three phases must be
specified.
a3
Amplitude compensation factor for winding 3.
s3
Vector group for winding 3.
Settings provided: All usual groups of connection with
designation of the circuit (y = star, d = delta, z = zigzag)
·
phase-angle adjustment of the winding 3 voltage in rela-
·
tion to the winding 1 voltage in multiples of 30°.
CurrentInp3
defines the c.t. input channel for winding 3. The first channel
(R phase) of the two groups of three phases must be
specified.
The protection operates in a two-winding mode, if a third in-
put is not selected.
BlockInp
Binary address used as blocking input.
F: - not blocked
T: - blocked
xx: - all binary inputs (or outputs of protection func-
tions).
InrushInp
activates the inrush restraint, even though the transformer is
already energised.
This enables, for example, the inrush current resulting from
energising a parallel transformer to be detected and com-
pensated.
F: - not used
xx: - all binary inputs (or outputs of protection func-
tions).
