20. Technical data

General
Definitions
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
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.
IBase used by the tested function is set
4. Parameter
equal to the rated CT primary current.
UBase used by the tested function is set
5. Parameter
equal to the rated primary phase-to-phase voltage.

7. The rated secondary quantities have the following
values:
– Rated secondary phase current I
depending on selected TRM.
– Rated secondary phase-to-phase voltage U
within the range from 100 V to 120 V.
– Rated secondary power for three-phase system S
√3 × U × I

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.
