ABB REG670 - Technical Data

23. Technical data
General
IP11376-1 v2
M10993-1 v3
Denitions
Reference value The specified value of an influencing factor to which are referred the characteristics of the equipment
Nominal range The range of values of an influencing quantity (factor) within which, under specified conditions, the equipment meets the
specified requirements
Operative range The range of values of a given energizing quantity for which the equipment, under specified conditions, is able to perform its
intended functions according to the specified requirements
Presumptions for Technical Data
GUID-1E949E38-E04D-4374-A086-912C25E9F93C v1
The technical data stated in this document are only valid
under the following circumstances:
1. Main current transformers with 1 A or 2 A secondary
rating are wired to the IED 1 A rated CT inputs.
2. Main current transformer with 5 A secondary rating are
wired to the IED 5 A rated CT inputs.
3. CT and VT ratios in the IED are set in accordance with
the associated main instrument transformers. Note that
for functions which measure an analogue signal which
do not have corresponding primary quantity the 1:1 ratio
shall be set for the used analogue inputs on the IED.
Example of such functions are: HZPDIF, ROTIPHIZ and
STTIPHIZ.
4. Parameter
IBase used by the tested function is set
equal to the rated CT primary current.
5. Parameter
UBase used by the tested function is set
equal to the rated primary phase-to-phase voltage.
6. Parameter SBase used by the tested function is set
equal to:
– √3 × IBase × UBase
7. The rated secondary quantities have the following
values:
– Rated secondary phase current I
r
is either 1 A or 5 A
depending on selected TRM.
– Rated secondary phase-to-phase voltage U
r
is within
the range from 100 V to 120 V.
– Rated secondary power for three-phase system S
r
=
√3 × U
r
× I
r
8. For operate and reset time testing, the default setting
values of the function are used if not explicitly stated
otherwise.
9. During testing, signals with rated frequency have been
injected if not explicitly stated otherwise.
