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