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.

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.
