This part of IEC 61869 is applicable to inductive protective current transformers meeting the requirements of the IEC 61869-2 standard. It may help relay manufacturers, CT manufacturers and project engineers to understand how a CT responds to simplified or standardized short circuit signals. Therefore, it supplies advanced information to comprehend the definition of inductive current transformers as well as their requirements. The document aims to provide information for the casual user as well as for the specialist. Where necessary, the level of abstraction is mentioned in the document. It also discusses the question about the responsibilities in the design process for current transformers.

This document specifies marking codes for fixed inductors. The colour code specified in Clause 3 gives a colour coding for fixed inductors. It is intended for use with the values of the E3 to E24 series as specified in IEC 60063. The code specified in Clause 4 gives a system for marking inductance values by means of digits and letters. The code specified in Clause 5 gives a system for marking the tolerance on inductance values by means of letters. The code specified in Clause 6 gives a system for marking of date codes on fixed inductors by means of letters and digits.
