PC57.13.7 - Standard for Current Transformers with a Maximum mA Secondary Current of 250mA

The purpose of this standard is to provide the performance requirements for electricial system and test interchangeablility for current transformers with milliampere output. These current transformers are for both indoor and outdoor applications.This standard is intended to define the requirements for current transformers with a maximum secondary output current of 250 milliamperes. These requirements of ratios, accuracy classes, burdens and test methods supplement, but are subordinate to, IEEE C57.13-2008, Standard Requirements for Instrument Transformers.
