19. 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:
• 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
30
set for the used analogue inputs on the IED, For example,
HZPDIF.
• Parameter IBase used by the tested function is set equal to
the rated CT primary current.
• Parameter UBase used by the tested function is set equal
to the rated primary phase-to-phase voltage.
• Parameter SBase used by the tested function is set equal
to sqrt(3)* IBase* UBase for three-phase power system.
