IEEE - C57.13.7
Standard for Current Transformers with Maximum Milliampere Secondary Current of 250 mA
|Publication Date:||5 December 2018|
This standard is intended to defi ne the requirements for CTs with a maximum of secondary output of 250 mA. These requirements of ratios, accuracy classes, burdens, and test methods supplement but are not subordinate to IEEE C57.13. These transformers are for both indoor and outdoor applications.
The purpose of this standard is to provide the performance requirements for electrical system and test interchangeability for CTs with milliampere output.
