Abstract

1 Scope

This part of IEC 61869 specifies the requirements for the safe design, 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.

NOTE The possibility of including additional safety requirements, specific to low-power instrument transformers, is currently under consideration.
