Scope
This standard is intended to define the requirements for current transformers with a maximum of secondary output of 250 milli-amperes. These requirements of ratios. Accuracy classes@ burdens and test methods supplement but are not subordinate to IEEE C57.13? Standard Requirements for Instrument Transformers. Purpose The Purpose of this standard is to provide the performance requirements for electrical system and test Interchangeability for current transformers with milli-ampere output. These transformers are for both indoor andoutdoor applications
