Overview
This part of IEC 61869 specifies the requirements for the safe design and operation, and tests for the safety of instrument transformers whose highest voltage for equipment is higher than 1 kV AC or 1,5 kV DC. Low power instrument transformers are not covered by this document. Typical applications involve the use of instrument transformers whose highest voltage for equipment is higher than 1 kV AC or 1,5 kV DC.
