Specifications of instrument transformers used in UCTE interconnecting 1

[DFilipovic]

Hi everyone! My question is: What are the specifications (accuracy class, rated burden, special requests...)of instrument transformers used for measurement of electric energy exchange between two countries inside UCTE? What voltage transformers are used: capacitor or inductive? I need information for all countries I can get. Thanks!

a)Voltage and current transformers at the accounting points should have an accuracy class rating of 0.2.
b) Current transformers should have 2 cores for measurement purposes
c) voltage transformer cables should be designed in such a way that a voltage drop is
reduced to 0.1% or less of the nominal voltage.
