Evaluation of Methods for Applying IEEE1584-2018 Equations for Low Voltage Current Limiting Fuses

This paper will propose methods for applying the standard equations of IEEE1584-2018 to address the issues of current limitation, the single pole nature of fuses, and current imbalance not covered by these equations. The goal is to use typical fuse data such as total clearing curves and let-through...

Description
Summary:This paper will propose methods for applying the standard equations of IEEE1584-2018 to address the issues of current limitation, the single pole nature of fuses, and current imbalance not covered by these equations. The goal is to use typical fuse data such as total clearing curves and let-through current data in equations developed for prediction of arc flash hazards. This approach yields calculations consistent with the results of lab tests using current limiting fuses.
