Each primary protective device required for the delta-to-wye connectedtransformer shall be selected so the characteristics of the operating band is withinthe transformer parameters, which shall include a parameter equivalent to 58% ofthe withstand point to afford protection for secondary line-to-ground faults. Thetransformer damage curve shall be included for the transformer when the selectedprotective device is not within the associated parameters.8. Molded case circuit breakers shall be separated from each other and theassociated primary protective device by a 16% current margin for coordinationand protection in the event of secondary line-to-line faults.9. The protective device characteristics or operating bands shall be suitablyterminated to reflect the actual symmetrical fault currents sensed by the device.10. The Contractor shall note that the drawings and specifications indicate thegeneral requirements for motors and motor starting equipment. High voltage andlow voltage equipment furnished shall be determined in accordance with theresults of the protection coordination study.11. The study shall include verification of equipment ratings and settings. Theresults of the study shall be submitted before preparing shop drawings.
