27. 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
• Maximum 176 binary input channels may be activated
simultaneously with influencing factors within
nominal range.
• The stated operate time for functions include the
operating time for the binary inputs and outputs.
• Maximum 72 outputs may be activated simultaneously
with influencing factors within nominal range. After 6
ms an additional 24 outputs may be activated. The
activation time for the 96 outputs must not exceed
200 ms. 48 outputs can be activated during 1 s.
Continued activation is possible with respect to
current consumption but after 5 minutes the
temperature rise will adversely affect the hardware
life. Maximum two relays per BOM/IOM/SOM should
be activated continuously due to power dissipation.
BOM/IOM/SOM should be activated continuously due
to power dissipation.
• Maximum two relays per BOM/IOM/SOM should be
activated continuously due to power dissipation. The
stated operate time for functions include the
operating time for the binary inputs and outputs.
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.
4. Parameter IBase used by the tested function is set
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.
SBase used by the tested function is set
6. Parameter
equal to:
IBase × UBase
– √3 ×
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 and BOM module are
used if not explicitly stated otherwise.
All reset times are measured using BOM output
contacts if not explicitly stated otherwise. The
operate/reset times are determined by
characteristics of the output module used.
9. During testing, signals with rated frequency have
been injected if not explicitly stated otherwise.
1 All declared operate times are with BOM module
0. unless specified. All the declared operate (trip) times
can be reduced by 3-4 ms when using SOM module.
